Very Fast Mechanical Mini Car vs Simplest Electromagnetic Train

This is speed challenge of simplest electromagnetic train 1.5V (compared with super clockwork mini car). Best performance is 4:40 ※ In this video's Lithium battery has safety holes for gas. ※ Symbol of Φ is magnets diameter. ※Friction = advantage about friction The standard written on the battery in this video is Alkaline (AA LR6 1.5V), Lithium (AA L91 FR6 1.5V) 【Run outside the coil】 /watch/UDurreODM1YDr 【How to make】 /watch/wJPBvbcXeXIXB 【1st model - 12 million views】 /watch/UAzO92J0b9J0O This electromagnetic train is made of neodymium magnets (super strong magnets), copper wire and a dry cell battery. 【My YouTube Channel】/channel/UCuDG1RIJehn2kTPB95DPixA 【Structure and How to make】 It's possible to get such power using a dry battery, neodymium magnets (super strong magnets which plated with metal) and some bare copper wires. 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 How about making this World's simplest electric train. Thank you for watching Very Fast Mechanical Mini Car (choro-Q) vs Simplest Electromagnetic Train
