Lenz's Law with Copper Pipe

Lenz's Law with Copper Pipe

MIT Department of Physics Technical Services Group

Added over 2 years ago | 00:01:38 | 5892 views

A magnet is dropped down a conducting copper pipe and feels a resistive force.  The falling magent induces a current in the copper pipe and, by Lenz's Law, the current creates a magnetic field that opposes the changing field of the ...
