  3. Cavity magnetron - Wikipedia

    en.wikipedia.org/wiki/Cavity_magnetron

    A cavity magnetron generates microwaves using the interaction of a stream of electrons with a magnetic field, while moving past a series of cavity resonators, which are small, open cavities in a metal block. Electrons pass by the cavities and cause microwaves to oscillate within, similar to the functioning of a whistle producing a tone when ...
