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.
Length: 320 mm approx.
Diameter: 15 mm approx.
(includes 2 plastic caps so that the tube can be used as a container).
