It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, for school physics lab equipment.

Specifications

What Is the Small Magnetic Compass Used For?

Placed on paper beside a bar or horseshoe magnet, the small compass shows the local field direction. Students mark both ends of the needle with pencil dots, move the compass forward to the last dot and repeat, then join the dots into a field line. The small diameter follows curved field lines closely and helps locate neutral points.

It also shows the magnetic field around a straight wire or coil carrying current, a key part of any magnetism experiment kit. Store compasses away from strong magnets, which can weaken or reverse the needle, and check that each needle settles north–south before a practical begins.

What to Specify When Ordering

• Diameter: 18 mm or 20 mm (both appear in the listing)
• Quantity, for example one compass per student pair for plotting work
• Whether magnets or iron filings are needed in the same order

Horse Shoe Magnets (Product Code: SCL-421/107) are U-shaped permanent magnets used to create a concentrated magnetic field between two close poles for magnetism and electromagnetism experiments in schools. Bending the magnet brings its north and south poles side by side, producing a strong field in the gap, which makes them standard physics lab equipment. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Are Horse Shoe Magnets Used For?

Because the field between the poles is strong and concentrated, a horseshoe magnet is the usual choice for the force-on-a-conductor experiment: a wire carrying current between the poles jumps sideways, demonstrating Fleming's left-hand rule. Moving a wire or coil through the gap while it is connected to a galvanometer shows electromagnetic induction.

Students also sprinkle iron filings on paper laid over the poles, or trace field lines with a small compass, to see how the field crowds across the gap. Store the magnets in pairs with unlike poles together or with a soft-iron bar across the poles, keep them away from electronic devices, and avoid dropping them, since knocks weaken permanent magnets over time.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies these horseshoe magnets from Ambala, Haryana, India. The company sources them for schools, colleges, dealers and importers who need permanent magnets for field-plotting and electromagnetism practicals, and can quote them with compasses and filings for a complete magnetism set. Company details are on the ScienceLab company profile.

Items used with horseshoe magnets in magnetism practicals:

• Magnetic Compass Small Size — plotting the field between the poles
• Iron Filling — a quick view of the field pattern
• Electromagnet for Demo — comparing a switchable field with a permanent one
• Economy Alnico Bar Magnets — straight magnets for comparison
• Steel Horseshoe Magnet — another horseshoe magnet in the catalogue

More magnetism and electricity apparatus is in the Physics Lab category.

Frequently Asked Questions

Are Horse Shoe Magnets permanent magnets?
Yes, Horse Shoe Magnets (SCL-421/107) are permanent magnets, so they stay magnetised without any power supply. This differs from an electromagnet, whose magnetic field is produced by a current and can be started and stopped by switching that current.

Why is the horseshoe shape useful?
The horseshoe shape brings the two poles of Horse Shoe Magnets close together, creating a strong magnetic field in the gap between them. That concentrated field makes experiments such as the force on a current-carrying conductor and electromagnetic induction easier to observe in class.

What sizes of Horse Shoe Magnets are available?
Size, pole gap and magnet material for Horse Shoe Magnets are not stated on this page. Tell us the dimensions or field strength your experiment needs through the ScienceLab contact page, and the quotation will describe the magnets offered before you order.

How should Horse Shoe Magnets be stored?
Store Horse Shoe Magnets with a soft-iron bar across the poles or in pairs with unlike poles together, away from electronics and bank cards. Avoid dropping or heating them, since knocks and heat can weaken a permanent magnet over time.

Who supplies the Horse Shoe Magnets?
Horse Shoe Magnets are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges, dealers and importers in India and international markets. They can be quoted together with compasses, iron filings and electromagnet apparatus.

Working Model of Electric Motor (Product Code: SCL-423/108) is an open-construction DC motor model used as a demonstration model in the physics lab to show how electrical energy is turned into rotation. Built in an acrylic body, it has a 2-pole armature, a disc-type commutator and a removable permanent magnet, and runs on 6–8 V DC. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Electric Motor Model Used For?

With the model connected to a 6–8 V DC supply through its 4 mm sockets, students watch the armature turn and can follow each step. Current enters through the phosphor bronze brushes, the disc commutator reverses the current in the coil every half turn, and the force between the coil and the permanent magnet keeps the rotation going. Because nothing is enclosed, the teacher can point to each part while it runs.

Taking away the permanent magnet stops the motor, a quick way to show that the magnetic field is essential, and reversing the supply leads reverses the direction of rotation. Keep the supply within 6–8 V, clean the commutator gently if running becomes uneven, and handle the acrylic body with care, as with any physics demonstration kit.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of this electric motor model. The model is made and assembled at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, institutions, dealers and importers. If a brush, magnet or other part needs replacing later, the manufacturer itself handles the request, so ask us. See the ScienceLab company profile.

• Banana Plug Connectors Leads — plug-in leads for the model sockets
• Demonstration, Electric Motor — another motor demonstration unit in the catalogue

See more electricity and magnetism models in the Physics Lab category.

Frequently Asked Questions

What voltage does the Working Model of Electric Motor need?
The Working Model of Electric Motor (SCL-423/108) operates on 6–8 V DC. A low-voltage DC source such as a battery eliminator or cells is connected through the model's pair of 4 mm colour-coded sockets, which link to the phosphor bronze brushes.

Which parts can students see in the motor model?
Every part of the Working Model of Electric Motor is visible because the construction is completely open: the 2-pole armature wound with enamelled copper wire on a plastic bobbin, the disc-type commutator, the phosphor bronze brushes and the removable permanent magnet, all in an acrylic body.

Why is the permanent magnet removable?
The removable permanent magnet on the Working Model of Electric Motor lets teachers show that a motor needs a magnetic field: with the magnet taken away, the armature stops. It also makes the field source easy to identify and discuss during the lesson.

How should the Working Model of Electric Motor be looked after?
Run the Working Model of Electric Motor only within 6–8 V DC, disconnect it after use, and keep the commutator and brushes free of dust. Clean the acrylic body with a soft damp cloth rather than solvents, and store the model covered.

Who manufactures the Working Model of Electric Motor?
The Working Model of Electric Motor is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Saha, Ambala, Haryana, India. Schools, dealers and importers buy directly from the manufacturer, which also handles repeat orders.

Working Model of Dynamo (Product Code: SCL425/109) is a hand-driven generator model used to show how mechanical energy is converted into electrical energy in school physics lessons. A hand-driven pulley turns the smaller dynamo pulley through a rubber belt for a step-up ratio, giving a clear demonstration of electromagnetic induction as the 2 bulbs supplied with it light up. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Dynamo Model Used For?

Turning the handle spins the armature beside the magnet, and the bulbs glow, showing directly that moving a coil in a magnetic field generates electricity. Turning faster makes the bulbs brighter, which lets students link the generated voltage with the speed of rotation, and the belt drive shows why a step-up pulley ratio is used.

Teachers often use it with the electric motor model to compare the two machines: the motor turns electrical energy into motion, while the dynamo turns motion back into electrical energy. Connect a galvanometer across the 4 mm sockets to watch the current, keep the rubber belt clean and seated on both pulleys, and turn the handle smoothly rather than jerking it.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Working Model of Dynamo. The model is built at the company's own licensed factory at Saha, Ambala, Haryana, India, on the same basic assembly as its electric motor model, and is supplied factory-direct to schools, colleges, dealers and importers.

Newton's Ring Model (Product Code: SCL-427/110) is a glass plate and convex lens assembly used to produce Newton's rings, circular interference fringes, for studying constructive and destructive interference in physics labs. This compact Newton rings apparatus holds both parts in a heavy aluminium frame 9 cm in diameter with a 5 cm aperture, and three spring-loaded screws adjust the contact pressure. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Newton's Ring Model Used For?

Where the convex lens rests on the flat glass plate, a thin wedge of air forms whose thickness grows outward from the point of contact. Light reflected from the top and bottom of this air film interferes, giving a dark central spot surrounded by concentric bright and dark rings, a direct picture of constructive and destructive interference.

Students can see the rings by eye in sunlight or under a fluorescent tube, where they appear coloured, and more sharply with a monochromatic source. Tighten the three spring-loaded screws evenly and only lightly, just enough to centre the rings, since excess pressure distorts the pattern. In college practicals the same principle is used with a travelling microscope to measure ring diameters.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the original equipment manufacturer (OEM) of the Newton's Ring Model. The aluminium-framed assembly is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, universities, dealers and importers.

Frequently Asked Questions

What does the Newton's Ring Model show?
The Newton's Ring Model (SCL-427/110) shows circular interference fringes formed in the thin air film between a convex lens and a glass plate. The alternating bright and dark rings are used to study constructive and destructive interference of light.

What are the frame size and aperture of the Newton's Ring Model?
The Newton's Ring Model has a heavy aluminium frame 9 cm in diameter with a 5 cm aperture. The glass plate and convex lens are held inside the frame, and three adjusting screws control how firmly they press together.

What light source is needed for the Newton's Ring Model?
Interference fringes are clearly seen when the Newton's Ring Model is viewed in sunlight, fluorescent light or monochromatic light. White light gives coloured rings, while a monochromatic source gives sharper alternating bright and dark rings suited to measurement.

How are the three screws on the Newton's Ring Model adjusted?
The three spring-loaded screws on the Newton's Ring Model set the pressure between the two glass surfaces. Tighten them evenly and gently until the ring pattern is centred and steady; over-tightening distorts the rings and strains the glass.

Who manufactures the Newton's Ring Model?
The Newton's Ring Model is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own factory in Saha, Ambala, Haryana, India. Colleges, schools, dealers and importers buy directly from the manufacturer.

It has a built-in 0–15 V DC, 150 mA regulated supply, two round meters for voltage and current, and 3 Zener diodes mounted behind the panel. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Zener Diode Board Used For?

Students wire the supply, meters and chosen Zener diode through the 4 mm sockets, then raise the voltage in small steps and record current against voltage. In forward bias the Zener conducts like an ordinary diode after a small threshold; in reverse bias the current stays tiny until the breakdown voltage, where it rises sharply while the voltage stays nearly constant, the property used for voltage regulation.

Having 3 Zener diodes on one board lets groups repeat or compare readings on a second device without rewiring the whole circuit. Start each run from 0 V, raise the supply slowly near breakdown, and switch off before changing connections. Used alongside a semiconductor diode kit, it completes the diode-characteristics practicals in a senior secondary physics lab.
