I seen this some years ago, and still have that useless 3' piece of 1/2" copper water pipe around, and the little burglar alarm contact magnet which is about 3/16 dia and a inch long.....same demo.....
that coil spring with the magnets is neat..... |

That is an example of Lenz's Law. I used it when teaching physics years ago. His smaller magnet would have worked nicely if he had used a smaller diameter pipe. I usually used a cow magnet. I remember back in the 70's when people were taping them on to their car's gas lines thinking that they would get better gas mileage. I even saw an article in Time magazine on it. People will believe anything!!! I should have had some stock in a cow magnet company back then. Naturally it didn't work and you don't here anything about it anymore.
