How do Microwave Ovens work? + more videos | #aumsum #kids #science #education #children

A microwave oven is basically a metal box containing a magnetron. It heats or cooks food much faster and more evenly as compared to a conventional oven. When switched on, the magnetron converts electricity into microwaves. Microwaves penetrate the food and excite water, fat and sugar molecules, generating heat and thus, helping us to heat up or cook the food.

Also note that, conventional ovens heat the food from outside in. Hence, the outer surface of the food is exposed to heat for a longer time, thus causing the food to cook unevenly. However, in microwave ovens, as microwaves penetrate the food, the food is cooked more evenly in less time. Thus, nutrient loss is less as it is exposed to heat for less amount of time.
