A magnetron is a device that generates microwaves using the principles of LC oscillation. It is the main component of a microwave oven and is responsible for producing high-powered microwaves. The magnetron is an oscillator where electrons are emitted from a hot cathode and whirl past resonant cavities to produce microwaves. The microwaves generated by the magnetron travel through a waveguide and are distributed into a metal cavity where the food is cooked. The waves are absorbed by the food and excite water molecules in the food, which then transfer heat throughout the food, cooking it. The radiation emitted by the magnetron is 2.4 gigahertz, which is relatively low and not harmful to humans. However, the magnetron is a kilowatt device, which means it is very high-powered and can burn you.
