A magnetron in a microwave oven con

A magnetron in a microwave oven converts electric energy into microwave energy. When the magnetron emits microwave energy at a frequency of 2450 MHZ, the water molecules placed in the microwave oven oscillate at a frequency of 2.45 billion times per second. The core component of producing high frequency electromagnetic field is magnetron. Food molecules vibrate in a high-frequency magnetic field, and molecules collide with each other and rub to produce heat energy, resulting in food being heated. Microwave ovens use this heating principle to cook food. Microwave is an electromagnetic wave, which is not only much larger than the usual radio wave. The invisible microwave can penetrate the food up to five cm deep, and make the water molecules in the food move with it. The intense exercise produces a lot of heat energy, so the food is cooked. This is the principle of microwave heating. It also has a "personality ": it reflects when it touches a metal, and the metal simply can't absorb it or conduct it; it passes through insulating materials such as glass, ceramics, plastics, but it does n' t consume energy; it doesn't pass through a food containing water, and its energy is absorbed, and when cooking food in a regular stove, the heat is always driven from the outside of the food
