Homopolar motor

Cooper is not magnetic. Today on class we worked on building a motor, to make a motor it needs to have a strong circuit, but it cant´t be very strong because if it was really strong the wire would touch the battery and the energy would´t be allowed to pass through the wire.  When there is a electric current flowing, a magnetic field starts flowing around the cooper so it can becomes magnetic. The magnet has to go in the negative side and the wire goes around the battery.
This project helped me understand how motors of cars work and what happens when you move the car switch and it goes backwards. The motors are used in our everyday life; cars, blenders, and washing machines are some examples.
