How Does An Electric Motor Work?

Electric motors work by the help of electromagnetism. But there are certain motors that work with the help of 'electrostatic forces' and the 'piezoelectric effect'. The most important factor by which an electric motor works is by the mechanical force present on every current carrying wire inside the magnetic field. This mechanical force is described as the 'Lorentz force law'. This law is applicable to both; the wire and the magnetic field.  

In an electric motor the part which rotates the motor is known as the rotor.  The part which remains stationary is known as the 'Stator'. When the voltage or current is turned on for the electromagnetic motor, either the Rotor or Stator will serve the purpose for the electric motor to work.
