How magnetron works?

A magnetron is a type of vacuum tube that generates microwave radiation by utilizing the interaction between electric and magnetic fields. It consists of a cathode that emits electrons, which are then influenced by a strong magnetic field, causing them to spiral and produce microwave oscillations. These oscillations are amplified and emitted as microwaves through a resonant cavity structure. The resulting microwaves can be used in various applications, such as radar and microwave ovens.
