An electric motor is a device that converts electrical energy into mechanical energy. It works by using electromagnetic principles to create motion. When electricity flows through coils of wire in a magnetic field, it generates a force that causes the motor's rotor to spin, producing mechanical power. Electric motors are widely used in various applications, from household appliances like fans and washing machines to industrial machines and electric vehicles. They come in different types, such as AC motors and DC motors, each suited for specific tasks and efficiency requirements.
