General Motor

    We can see all kinds of motors in our daily life. The most common kind is  in cars. The motors in car are generated by fossil fuel. It turned fossil energy to thermal energy  and then into kinetic energy.

But this is not the motor we are going to build. This motor was invented by Thomas Edison. By using electronic current to create magnetic field and by turning the + and - side to lead the motor move. 

The first time i saw a motor was on a model car when i was in primary school. And it used the Edison motor to generate its power. 

I always saw boys playing it and show off their new motors. And I also saw them messing up with it by getting rid of the shell and using the part inside as a spinning top.
