===== Description =====
When the yoke magnet is rotated, the non-magnetic brass ring appears locked and spins with the motion of the magnet.
The yoke magnet is supported by a ring of ball bearings between the white and red plate, which allows the magnet to spin in the vertical axis.
===== Purpose =====
This is a demonstration for Faraday's and Lenz's Laws. The ring moves to resist the change in flux that is caused by rotating the magnet.
===== Apparatus =====
===== Setup =====
Ensure that the ring is relatively centred within the yoke magnet by moving the thread and adjusting its length if necessary.
