Microwave ovens use a magnetron strong electric waves with a frequency of 2.5 GHz radio, to generate, which means that the wave vibrates 2.5 billion times per second. Radio waves in this band are absorbed by water, fat and sugar converted (and directly into the atomic motion = heat) and are partially absorbed by most plastics, glass or ceramic.
Microwave absorbing moisture in foods especially to heat, H2O, very few electrons in the molecule is water, and everything is in motion (resonance) of the electrical wave (vibration = heat) such as water and foodstuffs are heated.
Metals are on the other side can move freely full of electrons. As these electrons carry current, metal is good conductor of electricity. In a microwave, these electronsvibrate protect foods from radio waves by reflection. Some electrons move very quickly and directly into the metal on the outside air. It is the electrical discharge.
When a metal container is near the wall of a microwave oven, electric shock (sparks and high COP) between the wall and the metal container that can microwave to cause development problems. For example, the reflected waves from the antenna of a magnetron, resulting in an increase in temperature. Violence unloading of food can also inject into the oven.
The discharge may be possible deterioration of the magnetron, the electric discharge then produces more easily than compounds the problem. This can ultimately the oven no longer works, long before they should, if Used right.
Metallic films, such as fast food containers and aluminum can be used in the microwave, but they must be placed in the center and reduce the discharge side of the furnace and sparks. If it that cause the oven off and stop with aluminum foil as the weather damage the oven.
It is not packed properly cooked, as demonstrated by the role of microwaves.
If a (for example, is cup) object has a very thin layer of metal inside, within, say, a logo, so the heat can cause them to melt.
