The microwave frequency it produces is 2450 megahertz. Microwaves heat food like the sun heats your faceby radiation.
The cooking cavity of a typical microwave oven.
Microwave oven principle of operation. Working Principle of Microwave Oven Microwave ovens work on the principle of conversion of electromagnetic energy into thermal energy. Electromagnetic EM energy refers to the radiation waves comprising an electrical field and magnetic field oscillating perpendicular to each other. A microwave oven is a microwave generator.
The microwave frequency it produces is 2450 megahertz. This type of microwave has the characteristics of when it comes to foods containing water such as meat eggs vegetables and the microwaves. Also the same water molecules in the food fluctuate with their frequency.
The principle of the microwave oven is that when the magnetron is turned on the magnetron begins to release energy and then it is converted into heat. This heat is used to heat food. The magnetron is translated as an electrovacuum diode which consists of a copper anode.
This is the most expensive part of the oven. Microwave oven is one of the most widely used household appliances. Most of homes and most of conveniences store and restaurants have microwave oven.
The reason for its popularity is that it cooks food in an amazingly short amount of time. They are also extremely efficient in their use of electricity because a microwave oven heats only the food nothing else. In this article well discuss the mystery behind the magic of meals in a minute with microwave.
Microwave ovens are so quick and efficient because they channel heat energy directly to the molecules tiny particles inside food. Microwaves heat food like the sun heats your faceby radiation. The cooking cavity of a typical microwave oven.
This strong metal box stops harmful microwaves from escaping. A microwave oven works as follows. Electrical energy in the form of low-voltage alternating current and high-voltage direct current is transformed and converted into direct current.
A magnetron uses this direct current and generates microwaves with a frequency of 2450 megacyles per second or 245 GHz gigahertz. What is the working principle of the microwave oven transformer When the magnetron of the microwave oven transformer works an oscillating current flows in the secondary high-voltage winding of the transformer causing the iron core to generate magnetic saturation. Bill details how a microwave oven heats food.
He describes how the microwave vacuum tube called a magnetron generates radio frequencies that cause the wate. A microwave oven commonly referred to as a microwave is a kitchen appliance that heats and cooks food by exposing it to electromagnetic radiation in the microwave spectrum. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating.
The microwave oven is intended for domestic use only to cook defrost reheat and can food. Any other use is not permitted. Do not use the microwave oven to store or dry flammable materials.
If such items are dried in the microwave oven the moisture contained in the material evaporates causing the items to dry out and spontaneously combust. Even though microwave ovens are part of daily household appliances people are still worried about the foods nutritional and safety aspect.

Electromagnetic waves in this frequency band are used in a variety of applications microwave ovens in homes industrial heating cellular phones UHF TV broadcasts ship and airplane navigation radar for weather observation and aerospace communications. Kinds of Electromagnetic Waves Principle of Microwave Heating.
When an electric field. The microwave oven is intended for domestic use only to cook defrost reheat and can food. Any other use is not permitted.
Do not use the microwave oven to store or dry flammable materials. If such items are dried in the microwave oven the moisture contained in the material evaporates causing the items to dry out and spontaneously combust. Microwave oven is an appliance which makes use of microwaves as its basic force in enabling the cooking activities.
It seems to be a gift to all those individuals. Who find the use of normal forms of cooking to be quite annoying 523 views.
