Electromagnet with Keeper (Product Code: SLE/PHY/95) is a U-shaped electromagnet used to demonstrate the magnetic effect of an electric current in school and college physics labs. Its circular-section core is wound with insulated copper wire, carries an armature with a hook for hanging loads and runs from 4-6 volts DC, so students can switch a magnetic pull on and off at will. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Electromagnet with Keeper Used For?

With the supply connected, the armature is pulled firmly onto the pole faces, and loads hung from the carrying hook show how strong the magnetic force is; switch off and the armature drops away. Students can compare the lifting effect at different voltages within the 4-6 V DC range, or reverse the current and use a plotting compass to see the poles swap. It is a classic electromagnetic kit item for school practicals on the magnetic effects of current.

Store the electromagnet with its keeper across the poles and away from loose steel items. Do not exceed the stated DC supply, and switch off between readings so the winding does not get warm.

Lenz's Law – Open & closed loop (Product Code: SLE/PHY/96) is an electromagnetic induction demonstration used to show Faraday's law of induction and Lenz's law in school and college physics lessons. Passing a magnet through the complete loop makes the device move, while the split loop does not move at all, so students see that an induced current, not magnetism alone, causes the effect. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Lenz's Law Loop Apparatus Used For?

Moving a magnet into the closed loop induces a current in it, and by Lenz's law that current sets up a magnetic field opposing the change, so the loop is pushed away from, or drawn after, the moving magnet. Repeating the action with the split loop produces no movement, because the break stops any current from circulating. This side-by-side comparison makes the apparatus an effective electromagnetic induction kit for explaining why induced currents always oppose the change that creates them.

Move the magnet smoothly, then try faster and slower passes so students can relate the size of the response to the rate of change of magnetic flux. A strong magnet gives the clearest result; keep magnets away from meters and electronic devices while the demonstration is being set up.

What to Specify When Ordering

• Number of units, for a single teacher demonstration or for group work.
• Whether a suitable strong magnet should be quoted with the apparatus.
• Delivery location for the quotation.

OEM Manufacturer

ScienceLab is the name under which Jain Scientific Equipments Private Limited trades, and the company manufactures this Lenz's law apparatus as the OEM at its own factory at Saha, Ambala, Haryana.

More electromagnetism apparatus is listed under Physics Lab Equipment.

Frequently Asked Questions

What does the Lenz's Law – Open & closed loop demonstrate?
The Lenz's Law – Open & closed loop apparatus demonstrates Faraday's law of induction and Lenz's law. A magnet passed through the complete loop makes the device move, showing that an induced current creates a field opposing the change in flux.

Why does the split loop not move?
No movement at all occurs with the split loop of the Lenz's Law – Open & closed loop because the gap prevents a current from circulating. With no induced current there is no opposing magnetic field, and so no force acts on the loop.

Is a magnet included with the Lenz's law apparatus?
The Lenz's Law – Open & closed loop listing describes passing a magnet through the loops but does not confirm that a magnet is supplied. Ask us through the contact page and a suitable magnet can be added to your quotation.

Eddy Current Unit (Product Code: SLE/PHY/97) is a copper-tube demonstration used to introduce eddy currents and electromagnetic braking in school and college physics. Two test masses, one of steel and one a neodymium magnet, are dropped down a 33 cm copper tube, and students see the magnet fall more slowly than the steel mass. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Eddy Current Unit Used For?

As the neodymium magnet falls, its moving field induces circulating eddy currents in the copper walls, and these currents produce their own field that opposes the downward motion. The steel mass is not a magnet, so it induces no such currents and simply falls freely, which turns the two drops into a fair test with a striking difference. Teachers use the result to connect Lenz's law with real applications such as magnetic braking, making this one of the simplest physics demonstration kits for showing induction without meters.

Hold the tube upright over a soft surface or catch the masses at the bottom, and time each drop with a stopwatch if students are to compare results in numbers. Keep the neodymium magnet away from the steel mass, electronic devices and fingers, because strong magnets can snap together sharply.

What to Specify When Ordering

• Number of units, for a teacher demonstration or for several student groups.
• Whether spare test masses (steel or neodymium magnet) are needed.
• Delivery location for packing and freight.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM of this eddy current apparatus and makes it at its own factory at Saha, Ambala, Haryana. Physics departments, dealers and importers can order it directly from the manufacturer, and if a test mass goes missing a replacement can be requested from the same source.

Explore more apparatus in Physics Lab Equipment.

Frequently Asked Questions

How does the Eddy Current Unit work?
In the Eddy Current Unit, a neodymium magnet falling through a copper tube induces eddy currents in the tube walls. Those currents create a magnetic field that opposes the magnet's downward motion, so it falls more slowly than the steel test mass.

What is included with the Eddy Current Unit?
The Eddy Current Unit includes a 33 cm copper tube and its test masses: one steel mass and one neodymium magnet. Together they let students compare an ordinary fall with a magnetically braked fall through the same tube.

Why does the Eddy Current Unit include a steel mass?
The steel mass in the Eddy Current Unit acts as the control. Because it is not a magnet, it induces no eddy currents and falls freely, so the slower fall of the neodymium magnet can be attributed to induced currents.

How should the neodymium magnet be handled?
The neodymium magnet in the Eddy Current Unit is strong, so handle it with care: keep it away from electronic devices and other magnets, and avoid trapping fingers. Younger pupils should use the unit under teacher supervision.

Who manufactures the Eddy Current Unit?
The Eddy Current Unit is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM at its own factory in Ambala, Haryana, India, and is supplied direct to schools, colleges, dealers and importers.

What does a quotation for the Eddy Current Unit need?
A quotation for the Eddy Current Unit needs the quantity, whether spare test masses are required and the delivery destination. Orders are accepted from institutions and distributors in India and international markets through the contact page.

Inverted Tissue Culture Microscope (Product Code: SLE/M/34) is an inverted trinocular microscope used to observe living cells growing in flasks, bottles and dishes in cell culture, biotechnology and microbiology laboratories. Its objectives sit below a 180 x 150 mm stage, with extension plates for large bottles and micro-filter work. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for institutions buying cell biology equipment in India and abroad.

Specifications

What Is the Inverted Tissue Culture Microscope Used For?

Cells in culture settle and grow on the bottom of their vessel, under a layer of medium. An upright microscope cannot get close to them, so the inverted design turns the optics around: light comes from above and the objective looks up through the base of the flask or dish. Technicians use it to check confluence, cell shape and contamination before passaging, without opening the culture.

The long working distance of the listed 4x/0.1 objective (18 mm) suits thick-bottomed vessels. The two extension plates widen the stage for large bottles or micro-filter work, and the low-set focus knobs let the user rest their hands on the bench during long observation sessions. Attach one of the optional cameras to the trinocular port to record growth over several days.

What to Specify When Ordering

• The objectives you need for the quadruple nosepiece (only the 4x LWD objective is listed; ask us for the others)
• Camera option: micro-photographic, digital or CCD camera, if required
• Typical vessel sizes you will place on the stage

Force on a Conductor Apparatus (Product Code: SLE/PHY/98) is a rolling-axle demonstration used to show the force on a current-carrying conductor in a magnetic field, the motor effect behind Fleming's left-hand rule, in physics lessons. A brass axle resting on a pair of brass rails between the poles of a strong U-shaped magnet rolls away from the centre of the field as soon as a power supply is connected. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Force on a Conductor Apparatus Used For?

Current flows along one rail, through the brass axle and back along the other, so the axle itself becomes the conductor lying across the magnetic field. The resulting force pushes it along the rails, and reversing either the current or the magnet reverses the direction it rolls, letting students check Fleming's left-hand rule for themselves. It is a staple piece of physics practical equipment for showing the principle behind every electric motor.

Connect a low-voltage supply to the 4 mm socket terminals and switch on only briefly, since the path through the axle has very little resistance. Keep the rails and axle clean so the contact stays good, and store the U-shaped magnet carefully to preserve its strength.

What to Specify When Ordering

• Number of sets, for a teacher demonstration or for group practicals.
• Whether a suitable low-voltage, high-current supply should be quoted as well.
• 4 mm leads for connecting the rails to the supply.
• Delivery location for packing and freight.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, which manufactures this force-on-a-conductor apparatus as the OEM at its own factory at Saha, Ambala, Haryana. Schools, universities, dealers and importers buy it direct from the maker, and questions about a spare axle or magnet are answered at source. For vendor registration, institutional and tender buyers can use GSTIN 06AAECJ8618A1ZT and LEI 3358004HRD1JIVXKYX49. The company profile gives more information.

See more electromagnetism apparatus in Physics Lab Equipment.

Frequently Asked Questions

What does the Force on a Conductor Apparatus demonstrate?
The Force on a Conductor Apparatus demonstrates that a current-carrying conductor in a magnetic field experiences a force. When a supply is connected, the brass axle between the magnet's poles is repelled and rolls along the rails away from the centre of the field.

What parts make up the Force on a Conductor Apparatus?
The Force on a Conductor Apparatus comprises a strong U-shaped magnet, a pair of brass rails with 4 mm socket terminals, and a brass axle with plastic discs that rolls freely along the rails and completes the electrical contact between them.

What power supply does the apparatus need?
The Force on a Conductor Apparatus needs an external power supply unit connected to its 4 mm socket terminals, and the listing does not name a specific one. A low-voltage, high-current type such as the Electromagnetic Power Supply is worth discussing with us.

How does the apparatus relate to Fleming's left-hand rule?
The Force on a Conductor Apparatus lets students test Fleming's left-hand rule directly: field, current and motion are at right angles, and reversing either the current or the magnet makes the brass axle roll the opposite way along the rails.

Who manufactures the Force on a Conductor Apparatus?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Force on a Conductor Apparatus as the OEM at its own factory in Saha, Ambala, Haryana, India, and supplies it direct to schools, colleges, dealers and importers.

Electromagnetic Power Supply (Product Code: SLE/PHY/99) is a low-voltage, high-current bench supply used to power electromagnetism kits and Fleming's apparatus in school and college physics labs. It gives students access to 1 V a.c. from a 1-0-1 V a.c. output or 2 V d.c. (unsmoothed), tolerates short circuits and has a short-circuit current of 10 A. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Electromagnetic Power Supply Used For?

Electromagnetism practicals such as the force on a conductor need a large current at a very low voltage, which general-purpose school supplies are not built to give. This unit fills that gap: its 1 V a.c. and 2 V d.c. outputs let a low-resistance conductor carry a heavy current, so the forces and fields involved are strong enough to see. It is a specialised power supply unit for the physics lab, and because the d.c. output is unsmoothed it is meant for these demonstrations rather than for sensitive electronics.

The supply tolerates short circuits, and its transformer is guarded by thermal fuses and a slow-blow fuse, which suits student benches where leads are often shorted by mistake. Use leads suited to heavy current and switch off between experiments. At 208 x 155 x 115 mm with a carrying handle, it moves easily from bench to bench.

What to Specify When Ordering

• Number of units required per laboratory.
• The apparatus it will power, such as Fleming's apparatus or an electromagnetism kit, so suitability can be checked.
• Your mains supply, since the unit's input is 230 V ±10%, 50 Hz.
• Any heavy-current leads you want quoted with it.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies this electromagnetic power supply to schools, colleges, dealers and importers as part of its physics laboratory range. Quoting it together with the force-on-a-conductor apparatus or other electromagnetism kits it serves lets a department equip a complete practical in one order.

Induced Current Apparatus (Product Code: SLE/PHY/100) is a two-coil demonstration set used to show how a changing magnetic field produces an electric current in school and college physics laboratories. Teachers use it for electromagnetic induction and mutual induction lessons, and its soft iron core fits the primary cylinder to strengthen the effect. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as a practical electromagnetic induction kit for Indian classrooms.

Key Details

What Is the Induced Current Apparatus Used For?

The apparatus lets students see Faraday's law at work. Connect the secondary coil to a centre-zero galvanometer and the primary coil to a cell through a tap key: each time the primary circuit is made or broken, the needle kicks briefly, first one way and then the other. Pushing the energised primary into the secondary, or pulling it out, gives the same result and shows that only a change in magnetic flux induces a current.

Adding the soft iron core to the primary cylinder makes the deflections noticeably larger, a simple way to discuss how iron concentrates magnetic flux in transformers and induction coils. For clear readings, reverse the galvanometer connections to show that the direction of the induced current depends on the change, and switch the primary off between trials so the coil does not warm up. It is a dependable piece of physics lab equipment for schools in India preparing electromagnetism practicals.

OEM Manufacturer

The Induced Current Apparatus is made and assembled by ScienceLab, the trading name of Jain Scientific Equipments Private Limited, at its own licensed factory at Saha, Ambala, Haryana, India. As the original equipment manufacturer, the company produces this coil set at its factory rather than sourcing it from a trader, so schools, colleges, dealers and importers buy it factory-direct. Questions about a replacement coil or a spare soft iron core go straight to the manufacturer — just ask us. Learn more about the company on our company profile.

Related Physics Lab Equipment

These items complete an induction practical built around this apparatus:

• Galvanometer, Centre Zero Universal Meter — shows the direction and size of the induced current.
• One Way Key — makes and breaks the primary circuit cleanly.
• Connecting Wire — links the coils to the meter and the cell.
• Primary and Secondary Coil Set — an alternative coil pair for mutual induction work.
• Eddy Current Unit — extends the lesson to induced currents in solid conductors.

See the complete Physics Lab Equipment range.

Frequently Asked Questions

What is included with the Induced Current Apparatus?
The Induced Current Apparatus includes a primary coil of insulated copper wire wound on a cylinder with terminals, a secondary coil on a cylinder that receives the primary, and a soft iron core that fits the primary cylinder. A galvanometer, cell and leads are not part of the listing.

What else do I need to demonstrate electromagnetic induction?
To demonstrate induction with the Induced Current Apparatus you also need a sensitive centre-zero galvanometer for the secondary coil, a low-voltage DC source such as a cell for the primary, a tap key and connecting leads. We can quote these accessories together with the coils.

Why does the apparatus come with a soft iron core?
The soft iron core of the Induced Current Apparatus concentrates the magnetic field of the primary coil, so the change in flux through the secondary is larger. Students therefore see a bigger galvanometer deflection with the core in place than when the coils are used with air alone.

Who manufactures the Induced Current Apparatus?
