Lenz’s Law – Splat The Rat
Lenz's Law demonstrated using the Splat The Rat demonstration lending itself to a fun classroom activity based on a village fete challenge.
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 Splat The Rat 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.
