Demonstrate the amazing Lenz's law with this apparatus.


Two test masses are sent through a 33 cm copper tube. One mass drops quickly, but the other seems to defy gravity by slowing as it falls! Why? Because one mass is steel, and the other is neodymium, a magnet that creates a moving magnetic field, that produces an electrical (eddy) current that resists its fall.
