An induction motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.

Some common applications of direct current include:

1. powering electronic devices
2. charging batteries
3. operating electric motors
4. welding metals
