Splat The Rat
Fun and dramatic demonstration of Lenz’s Law. Interactive and entertaining demonstration of induced currents and magnetic fields. 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.
