Description:

A copper plate is mounted as a pendulum in that swings freely in a plane parallel to the plate. When a magnet is placed so the copper plate passes between the magnet poles. This induces eddy currents in the plate. and the result is magnetic braking -- a force arises that opposes the motion of plate and the plate will quickly come to a stop,. Change the solid copper plate with a plate that has slits cut into it, The plate with slits will take longer to slow down and come to a stop because the eddy currents will be smaller in the plate with slits,.
