Lenz's Law, "Splat the Rat"
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 (as featured in the Lascells Science Silly Bus Show) 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 5s to exit the tube.
