How Do Microwaves Work With Electromagnets?

Microwave is a term used for oven that makes use of electromagnetic waves. Microwaves employ electromagnets to make use of the magnetic radiation that is created because of the application of electric current. The radiation is not harmful and is not the radiation that releases harmful alpha and gamma particles. The magnetic radiation from the electromagnet is used to warm up the food placed in the microwave oven.

The radiation light has certain wavelength and is longer than the normal wavelength of light. This light or radiation enters the food and make the water molecules in food line up in the direction of the radiation waves. Once lined up these particles also vibrate and create heat and thus heat up food. Electromagnets are also used to detect the opening and closing of the doors of the microwave.
