One application of magnetic fields in household appliances.

One thing that uses magnetic fields is the electric motor, which is used in many household appliances, such as electric fans, microwave ovens, and other small appliances. In this instance the electric motor has an electric current, giving it also this magnetic field. An electric motor converts electricity into mechanical motion.
