Faraday's and Lenz's law Demonstration Set
Product Code : SCL-PL-12395
Faraday's and Lenz's law Demonstration Set (SKU SCL-PL-12395) shows that a changing magnetic field induces a current in a coil, and that the induced current opposes the change producing it, using a neodymium magnet, guide tube, induction coil and copper ring for Class 12 and college electromagnetism. Science Lab Supplies manufactures the set at its HSIIDC Industrial Area factory, Plot 448, Saha, Ambala, India, and supplies schools, colleges, contractors and distributors.
Specifications
The set is built on a 265 × 185 × 60 mm base platform with an LED source and 4 mm safety socket. A PVC guide tube works with the large neodymium magnet, an impact cushion, a copper ring and a 5 A air-core induction coil.

Applications and Experiments for the Faraday's and Lenz's Law Set
The set demonstrates electromagnetic induction: moving the neodymium magnet through the coil induces an emf that can be detected through the 4 mm connections, and the closed copper ring shows the opposing effect predicted by Lenz's law. It is a clear electricity and magnetism lab kit for schools and colleges.
- Class 12 physics (electromagnetic induction): induced emf and the rate of change of flux.
- Lenz’s law: the current induced in the copper ring opposes the change in flux.
- B.Sc. electromagnetism: observing induced emf polarity with a galvanometer or data logger.
Keep the impact cushion in place so the magnet is not chipped when it lands.
Standard Scope of Supply
Each set includes the base platform with LED source and 4 mm safety socket, the PVC guide tube, the copper ring, the large neodymium magnet, the impact cushion, the air-core induction coil and two leads with black and red 4 mm plugs.

Frequently Asked Questions
What are the coil and tube specifications?
The air-core induction coil uses 23 AWG wire rated 5 A with 4 mm plug connections. The PVC guide tube is 31.6 mm outside and 30 mm inside, and the copper ring is 38 mm outside and 32 mm inside.
Is Science Lab Supplies the manufacturer or a trader?
Science Lab Supplies manufactures this demonstration set at its own facility in Saha, Ambala, India. As the maker, it prepares every quotation itself, so schools and distributors deal directly with the manufacturer.
Is the neodymium magnet safe for students?
Use it under supervision. The strong magnet can pinch fingers and snap onto steel objects, and it must be kept away from phones, cards and anyone with a pacemaker.
