magnetrons
Microwave oven cores
Magnetrons are vacuum tubes that generate microwaves by using magnetic fields to control the flow of electrons.
The technology powers microwave ovens, where magnetrons convert electricity into the radiation that heats food.
Magnetrons also appear in radar systems, where they produce the high-frequency pulses used to detect objects at a distance.
