Lenz's Law Demo

Pasco Lenz's Law Demo 

 

The Magnet Mass and the Non Magnetic Mass are attached to a bag and taped to the to of the apparatus. Please tape them back in place when you are finished with the demo.

*From Pasco's site

*Drop a mass through the 1.5 meter tube. It takes about half a second to drop. Then drop a magnet with an identical mass. It takes over 10 times as long to fall.
As the magnet falls, it generates a current in the walls of the tube, moving in one direction above the magnet and in the opposite direction below the magnet. Both currents obey Lenz's Law and induce magnetic fields that oppose the motion of the magnet.
