Demonstrate Lenz’s Law.
Two masses drop down a 33cm copper tube. One is steel, one is a neodymium magnet. When students see the magnetic mass fall more slowly than the steel mass, you can introduce them to electrical eddy currents.
These currents oppose downward motion through a moving magnetic field created by the falling neodymium magnet.
