ocr: How does an electric motor turn? MAGNETPOLESI FORCES ONWIRE COMMUTATOR Electromagnetic: forces makemost electric motors turn. In its simplest form, an electric motor is a loop of wire that turns between the poles ofa permanent magnet. When an electric current flows through the loop, magnetic fields form around it. These interact with the magnetic field of the permanent magnet, producing forces that push one side of the loop up and the other side down. To make the loop spin, once it hasreached a vertical position, the side of the loop that was being pushed upward needs to be pushed downward, an ...
