Magnetron

In electronics, a magnetron is a two-eklectrode valve in which the flow of electrons from a large central cathode to a cylindrical-shaped anode is controlled by crossed electrical and magnetic fields. The electrons gyrate in the axial magnetic field, their energy being collected in a series of slot resonators in the face of the anode.

magnetron

Thermionic valve (electron tube) for generating very high-frequency oscillations, used in radar and to produce microwaves in a microwave oven. The flow of electrons from the tube's cathode to one or more anodes is controlled by an applied magnetic field
