Demonstration of Lenz's Law with an Induction Motor
Kraftmakher, Yaakov
Physics Education, v40 n3 p281-284 May 2005
The interaction of a conductor with a time-dependent magnetic field is an important topic of electromagnetic theory. A computerized classroom demonstration shows how the eddy currents induced in the rotor of an induction motor cause its rotation or braking. Both phenomena are directly related to Lenz's law.
