Why does a magnet slow down in copper?
So why does a magnet fall slowly through a copper pipe? As a result of the magnetic repulsion created, a damping effect is seen. As gravity pulls the magnet downwards through the pipe, the magnetic field created by the eddy currents resist the magnetic field produced by the magnet, slowing it down.
Will a magnet stick to brass or copper?
Copper is not magnetic. Brass is a mixture (alloy) of copper and mostly zinc (zinc is not magnetic). As with testing precious metals, a magnet will not tell you if an item is made of copper / brass / bronze, but it will tell you if it isn’t.
