Magnetron?
Inside a microwave oven is a magnetron it helps generate microwaves by emitting electrons? mmm as Ed would say where are these electrons? We know a microwave works but are we misunderstanding how it really works maybe Ed would think so. " Protons and Electrons --- Are you sure they are not the north and south pole individual magnets?" " The invention of an electron came by a tricky method in using electricity in a vacuum tube. Normally whether it be a generator or a battery, the positive terminal will have to be connected to the negative terminal, but in the vacuum tube two batteries with different strength were used, the smaller battery was connected normally, but the larger battery's negative terminal was connected to the smaller battery's negative terminal, and the positive terminal was left alone. That connection gave the negative terminal a double dose of strength, and so it became hotter and could push more. It was called cathode and the...
