A cavity magnetron is a type of vacuum tube and microwave oscillator that generates high-frequency microwave radiation. It is widely known for its application in radar technology and microwave ovens. The fundamental principle behind a cavity magnetron involves the interaction of electrons emitted from a heated cathode and a magnetic field in a vacuum environment. ### Key Components: 1. **Cathode:** Emits electrons when heated.
Apparently, DC current comes in, and microwaves come out.
