Motors

Copper is not magnetic
A motor works by using electromagnetism to continually spin the wheels on the car without any external help besides a magnet and a closed loop. it works by having an insulated side of the copper wire and a exposed side so it can rotate properly, the wire itself is not magnetic but the electrons inside the wire from the closed loop cause it to have a electromagnetic field which has an attraction to magnets causing a magnetic field.
The stronger the magnet and bigger the coil of copper the faster it will spin and the stronger because it has a stronger attraction to the electromagnetic field.
