An electric motor is a device that converts electrical energy into mechanical energy. It works by using electromagnetic principles, where electric current flows through coils of wire, creating a magnetic field that causes a rotor to spin. This spinning motion can then be used to power various machines and appliances. Electric motors are commonly found in everyday items such as fans, washing machines, and electric vehicles. They come in different types, including AC motors and DC motors, each suited for specific applications. Their efficiency and reliability make them essential components in modern technology.
