Others who can't straighten the microwave oven are:
1, Avoid using metal utensils: As there are iron, aluminum, stainless steel, enamel and other utensils in the furnace, electric sparks will be generated when the microwave oven is heated, which will not only damage the furnace body, but also heat the food.
2. Avoid using closed containers: use wide-mouth containers when heating liquids, because the heat generated by food heating in closed containers is not easy to dissipate, which makes the pressure in the containers too high and easily leads to blasting accidents.
Extended data:
Microwave is a kind of high-frequency electromagnetic wave, which does not generate heat itself. There are microwaves everywhere in the universe and nature, but there are microwaves in nature. It can't heat food because they are scattered, not concentrated. Microwave ovens use internal magnetrons to convert electric energy into microwaves, which vibrate in food at a frequency of 2450MHz.
When microwave is absorbed by food, polar molecules in food (such as water, fat, protein, sugar, etc. ) will be attracted to swing at a speed of 2.45 billion times per second. The macroscopic manifestation of this oscillation is that food is heated.
