Microwave oven magnetron. This cavity magnetron essentially converts electrical energy into microwave energy. It consists of a cathode (hot filament) inside a high-powered vacuum tube (inside the black part at centre) within a magnetic field. The microwaves generated in the chamber are directed to the oven's food-heating compartment by the waveguide (pink tube at lower left).
