Drop a dry-erase maker cap and the strong magnet in to the vertically held aluminum pipe. Why do the magnet slower the the cap?
Answer :
As the magnet moves down the pipe it creates small electrical currents in walls of the pipe (Eddy currents). These electrical currents repel the magnet and cause it to fall slower.

A magnet is dropped down a copper pipe. In the walls of the tube, there is an induced voltage as the magnet falls. Many field lines that are appear where where there originally were no field lines. When there is a change in flux, there is an induced current in the conductor that generates the magnetic field opposing the change. Some opposing force arises in the pipe that pushes up on the magnet as its going down, therefore making it...
When a magnet is dropped through the copper pipe, why does it fall slower than the aluminum pellet? Is energy conserved when magnet falls? If not, where does the missing (or gained) energy go (or come from). How would this be different if the pipe was made of PVC?
