GCSE Physics - How the Electric Motor Works #80

The video explains how electric motors work, focusing on the motor effect where a current-carrying wire in a magnetic field experiences a force. The direction of this force depends on the current and magnetic field directions, determined by Fleming's left hand rule. A coil with current flowing through it experiences forces that cause it to rotate. To maintain continuous rotation, a split ring commutator swaps the current direction every half turn. This principle is used in various motors, and their power can be increased by adjusting current, coil turns, or magnetic flux density.
