04:02 04:02 It's possible to get such power using a 1.5 alkaline battery, neodymium magnets(something plated with metal) and a bare copper wire A point is that a magnet's diameter is bigger than a dry cell battery's diameter And an electric current flows to a coil through a neodymium magnets, and a coil will be an electromagnet only in an area between the magnet and the magnet. The electromagnet and a neodymium magnet poles repel each other at one side. The other side poles pull against each other. They work same direction, and it become a big force The phenomenon also continues at a movement destination.
