Question

What is a magnetron?

Answer 1

It is a vacuum tube that is specially designed to produce microwaves.  It is used an an oscillator tube.

Some magnetrons produce low-level microwaves, while the most common magnetrons inside microwave ovens produce high power microwaves (100s of Watts).

.

Answer 2

A magnetron is the gizmo-tron within a microwave oven that actually emits the coherent microwave energy that jiggles the molecules of food to make it hot. Think of it as a tiny nuclear particle accelerator, but different.

Answer 3

a vacccm tube in which the flow of ions from the heated cathode to the anode is controlled by a magnetic field externally applied and perpendicular to the electric field by which they are propelled ;used to produce very short radio waves
