How about making this with children to enjoy science? (Run outside the coil) -    • World's Simplest Electric Train 【Ver.2】   (Speed Battle) -    • Domino vs Simplest Electromagnetic Train   (Ver.1 - 9 million PV) -    • World's Simplest Electric Train   This is a kind of electromagnetic train. Please enjoy the World's Simplest Electric Train. 【My YouTube Channel】 In this video's URL    / @amazingsc   【Subscribe】 http://goo.gl/cckoxX 【Structure and How to make】 It's possible to get such power using a 1.5V alkaline battery, neodymium magnets (super strong magnets with 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. ※Another important point is magnets direction (e.g.) NS battery SN Thank you for reading. How about making this electromagnetic train for science fair projects?
