Handy demonstration apparatus for illustrating Lenz’s law and induction of eddy currents. A small steel cylinder and a magnet of the same weight fall at different speeds through a copper tube because the motion of the magnet causes eddy currents to be induced, resulting in a magnetic field which slows the fall of the magnet. Includes 2 plastic caps so that the tube can be used as a container.
