How do magnetrons work? - Explain that Stuff
网页2022年4月11日 · A magnetron's job is to generate fairly short radio waves. If you could see them, you could easily measure them with a school ruler. They're usually no shorter than about 1mm (0.04 in; the shortest division on a metric ruler) and no longer than about 30cm (12in; the length of a typical school ruler).
