MAGNETRON MWA7025 (#C08)

A magnetron is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field while moving past a series of open metal cavities (cavity resonators). Electrons pass by the openings to these cavities and cause microwaves to oscillate within. The frequency of the microwaves produced (the resonant frequency) is determined by the cavities' physical dimensions.

The magnetron serves as an oscillator, generating a microwave signal from direct current electricity supplied to the vacuum tube. The microwave radiation that the cavities produce is collected up and channeled by a kind of funnel called a waveguide into the cooking compartment of a microwave or rapid cook oven.
