How to make World’s Simplest Electric Train 【世界一簡単な構造の電車】
It’s possible to get such power using a 1.5V 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. Check out the video now.
