The magnetron generates microwave radiation by bouncing electrons around inside a vacuum filled cavity that is exposed to a strong magnetic field . This magnetic field forces these electrons to circle around inside the cavity, absorbing energy. Eventually, this energy is released as a microwave.

Microwave method consists of an electromagnetic radiation and lies between radio waves and infrared frequencies, and relative wavelength spans from 1 mm to 1 m. Dipole rotation and ionic conduction are the two fundamental mechanisms for transferring energy from microwave methods to the substance being heated.
