|title: Eddie Current Pendululm|
aka: Magnetic Brake
An aluminium plate pivots from a ring stand through a strong magnet. Without the magnet, it swings several times before coming to rest. With the magnet, it stop swinging in 2 or 3 cycles.
Another plate has slits to interupt the eddie currents and swings as if the magnet were not there.
Why do eddie currents reduce kinetic energy?
