How to have fun playing a physics friend? Very simple! Give him a simple comic souvenir called "Perpetual motion", assembled from ordinary and neodymium magnets. Making such a souvenir with your own hands is easy.
To make this homemade product you will need a round magnet from the speaker, several small neodymium magnets, a metal cover from a jar of powder, a plastic sleeve, as well as a self-tapping screw with a drill. Here, in fact, is the whole set of necessary materials.
The main stages of work
We take one neodymium magnet and glue the edge with one layer of electrical tape. Then, using a screw with a drill, we connect the magnet with a plastic sleeve. We also wrap an ordinary magnet with tape.
Next, we put ten neodymium magnets around a large magnet, and then we pull them together with a plastic screed (or something else that is at hand).
We insert a neodymium magnet with a sleeve inside the central magnet, then we install another small magnet on the side. Then we take a metal cover from a jar of powder (or another), drill a hole in it in the center and fasten it to a plastic sleeve.
The result is a strange design that does not even remotely resemble a perpetual motion machine. But at the same time, with the help of such a souvenir, one can "prove" in a joking manner that infinite energy does exist in nature.
