What Happens When You Drop A Magnet Through A Copper Tube?
Heinrich Emil Lenz was a German physicist that formulated a law of electromagnetic induction back in 1833. The most stripped down explanation of the law is that when a current is induced in a conductor, a magnetic field is generated that opposes the action that produces the current.
In other words, the magnet induced a current in the copper pipe, which in turn produced a magnetic field. The direction of this current then opposed the change in the magnet’s field, resulting in the magnet being repelled and thus falling more slowly.
