Today, almost every house, almost every kitchen, as well as virtually every office you can see this in the household appliance needed for cooking and heating food. He has become so commonplace that many people do not think, that there were times when the subject of kitchen interior was simply exotic. Invented, he was in the middle of last century, but it took decades before it has become firmly established in our everyday life. Jeff Sessions is open to suggestions. How it works is simple but above this ease of engineers, scientists, inventors worked for a long time. Microwave oven is unthinkable without electricity – that's how it works: to transform the energy of electric current into heat by creating a so-called radiation microwaves. West Lake Landfill is often quoted on this topic. This means that the frequency of exceeding the one which passed through conventional radio. The experiments in this field have led to what has been the phenomenon of heating of the material, consisting of polarized molecules under the influence of high-frequency waves.

Easily change direction of the electric field gradient causes the polarized molecules that are beginning to heat up due to friction that arises in connection with reorientation of molecules in a changing field. This is the physics of the process that occurs when you want to heat up food in your microwave. The peculiarity of his that just polarized molecules are heated, the unpolarized molecules changing electric field heating effects will not help. So chop on the porcelain plate is heated, the plate itself as well – no. But if you put a metal bowl that will high-frequency response that will lead to inevitable failure, as well as the need to repair microwave.

Chicken is heated due to the fact that it has a water – a substance consisting of electrically polarized molecules. Only by the presence of water in foods can be warmed by microwave waves. Oven-dry product, consisting only of non-polarized molecules, is heated in the oven of your will not. It was only thanks to that water is present in almost all foods, they can be heated in a microwave oven. The main component of any microwave oven – a magnetron, which just ensures the generation of the above microwave waves. Microwave housing protects us from excessive exposure. It was also invented a rotating device that provides uniform heating of food. Types of microwave ovens, there is a great set, but the above features are common to all. Today, virtually replacing the conventional microwave oven gas and electric stoves, the volume of their sales are comparable. And, of course, every woman will prefer warm foods in the oven, rather than using conventional heating methods, such as on a griddle. First, it is faster, and secondly, and most importantly, evenly heated throughout the volume, in contrast to traditional methods heating food in which the heat comes from the inside surface of the product. That's the advantage of uniform heating of food in the entire volume of microwave ovens has provided such a high popularity.
