Demountable Transformer Accessory Set No. 2 – Lenz’s Law Demonstration [0493]

The Demountable Transformer Accessory Set No. 2 is a specialist physics teaching resource designed to support the demonstration of Lenz’s Law and the effects of induced magnetic fields. Suitable for KS4, GCSE, and A‑Level physics, this accessory set extends the capabilities of a demountable transformer system by enabling clear, hands‑on investigations into electromagnetic damping.

This set allows students to observe how changing magnetic flux induces currents that oppose the motion producing them, as described by Lenz’s Law. The accessories are particularly effective for demonstrating magnetic braking and damping using pendulums, providing a dramatic and memorable illustration of electromagnetic induction principles.

By comparing the motion of pendulums with and without slits, students can clearly see how induced currents are reduced when current paths are interrupted, reinforcing understanding of the relationship between induced currents, magnetic fields, and energy dissipation.
