How a Microwave Oven Works

Engineer Rudy Dehn tells us how a magnetron works and how it cooks food in a microwave. Mr. Dehn helped develop both the 915 Mhz and 2.45 Ghz microwave oven at General Electric in the 1960s-80s. He shows us the cathode and anode and describes how microwave energy is created using a filament, magnets and resonating cavities. He takes apart a magnetron and shows us each part and what it does.
