Open and Closed Loop Lenz's Law Apparatus

This Lenz's Law apparatus includes both an open and a closed aluminum loop connected by a straight bar with a groove for placement on a needle. The loops are mounted on a blue cast iron base with a rod and needle support. The open and closed loop dimensions are identical, with an inner diameter of 1.82" and outer diameter of 1.98". The apparatus is designed for demonstrating both Lenz's Law and Faraday's Law, showing how a changing magnetic field induces an electromotive force and how the induced current opposes the change that produced it.
