Simple Electric Motor
#Physics #GCSE Looking at Flemings Motor Rule and how electric motors work starting with this very simple design. #iteachphysics #Science #STEM This design is nothing more than a coil of wire resting on two pieces of wire and a strong magnet. According to Flemings Left Hand Rule when a wire carrying an electric current comes into a magnetic field then movement happens.
