Copper is not magnetic. When we put an electric current flowing though it, a magnetic field starts flowing around the copper and it becomes magnetic, for example, when you connect one side of the copper to one side of the battery and connect a magnet at the other side of the battery and then make the copper touch the magnet the whole copper will start moving because a circuit is completed. In a car motor the metal sticks that are touching the wire are already magnetic thanks to the cable that is connected to them, this sticks make the copper magnetic instantly, the magent below the copper is pulling the copper and when the car is moving forward the copper starts spinning.
