Splat The Rat (Each)

Lenz's Law can be demonstrated using the standard Eddy Current Tubes whereby a
magnet falls through a copper tube at a slower rate than an un-magnetised
weight. The demonstration lends itself to a fun classroom activity based on
the village fete challenge of Splat the Rat. Two 'rats' are supplied, one
containing strong neodymium magnets and the other just a metal weight. 1m of
copper tube and a foam-covered rounders bat completes the kit. In use, the
challenge for the pupil is to hit the rat as it emerges from the tube. It
gives a dramatic demonstration of Lenz's Law since the magnetised rat takes
about 5 seconds to exit the tube. Dimensions: 1000 x 30 x 30mm Weight 0.3kg.
