The Magnetron is the most important appliance part of a microwave oven. It
is the source of microwave heating in a microwave oven.
The operating principle
of the microwave oven is as follows: the magnetron converts electrical energy in
a high electric field, forcing the moving water molecules, which leads to warm the
product. The Magnetron, creating an electrical field, sends it to the waveguide
in a working chamber in which a product containing water (water is a dipole, because
the water molecule is composed of positive and negative charges). The effects of
external electric field are to produce results that are beginning to polarize the
dipoles, ie dipoles are starting to turn. Turning the dipoles and the forces of
friction, this turns into heat.
The main advantage
of a microwave heating is quick cooking with full preservation of food and biological
value of the product. A microwave has high efficiency and does not adversely affect
of a microwave heating should be ambiguity in determining the time for cooking complex
dishes with different moisture content of each of the components, as well as absence
crisp crust in the cooking process.
