Faraday's Law Apparatus (Product Code: SLE/EAM/08) is an electromagnetic induction apparatus used to show and measure the pulse of electricity a falling magnet induces in a coil, in school and college physics labs. A small cylindrical magnet, supplied with it, drops down an acrylic tube through a movable coil, and twin coils of 150 and 300 turns let students compare results. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India, as part of its electromagnetic induction kit range.

A first run is purely qualitative: drop the magnet and watch the oscilloscope trace rise and then swing the other way as the magnet enters and leaves the coil, a direct picture of Lenz's law. Switching between the 150-turn and 300-turn coils then shows how the size of the induced pulse depends on the number of turns, while turning the magnet over reverses the trace. A PC-based oscilloscope makes this especially easy because each single-shot event can be captured, stored and compared on screen.
For senior students the apparatus becomes a quantitative investigation of Faraday's law. Sliding the coil to a different position on the tube changes how far the magnet falls before reaching it, and therefore its speed; students work out that speed from the equations of motion and plot pulse amplitude against it. It is compact physics lab equipment in India's senior classrooms that ties induction to mechanics in one practical. Place a soft pad at the bottom of the tube so the magnet is not chipped by repeated drops.
Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of the Faraday's Law Apparatus and makes it at its own licensed factory at Saha, Ambala, Haryana, India. The apparatus is built and assembled by the company itself rather than sourced from a trader, and it goes factory-direct to schools, colleges, dealers and importers. If you later need a replacement magnet or coil, ask us: spares and repeat orders are handled by the manufacturer. Read more on the company profile.

What comes with the Faraday's Law Apparatus?
The Faraday's Law Apparatus comes with the acrylic guide tube and its movable coil arrangement, twin coils of 150 and 300 turns, a small cylindrical magnet and full instructions. An oscilloscope is needed to display the pulse but is ordered as a separate item.
Does the Faraday's Law Apparatus need an oscilloscope?
Yes. The Faraday's Law Apparatus produces a brief pulse of electricity each time the magnet falls through the coil, and an oscilloscope is used to monitor that pulse and measure its amplitude. PC-based oscilloscopes are particularly suited because they capture single events.
Why does the Faraday's Law Apparatus have two coils?
The twin coils of 150 and 300 turns let students compare the induced pulse for two different numbers of turns on the Faraday's Law Apparatus, adding a second variable alongside magnet speed and showing how the induced voltage depends on the turns.
How do students change the magnet speed?
On the Faraday's Law Apparatus the coil is moved along the acrylic tube, which changes how far the magnet falls before reaching it. Senior students calculate the speed at the coil from the equations of motion and relate it to the measured pulse amplitude.
Who manufactures the Faraday's Law Apparatus?
The Faraday's Law Apparatus is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Quotations, repeat orders and questions about a spare magnet come straight from the manufacturer through our contact page.
What should a quotation request include?
For a Faraday's Law Apparatus quotation, send the product code SLE/EAM/08, the number of units, whether an oscilloscope should be quoted with it, and your delivery location. We supply schools and colleges across India and international markets.
Quotes for the Faraday's Law Apparatus come direct from the manufacturer. Write to us through the contact page or add it to the enquiry cart together with an oscilloscope or other induction apparatus.
