is a pretty simple device.\u00a0 It&#8217;s basically just a magnetron hooked up to a high voltage source.\u00a0 This magnetron directs microwaves into a metal box.\u00a0 These generated microwaves then bounce around inside the microwave until they are absorbed via dielectric loss in various molecules, resulting in the molecules heating up.\u00a0 Matter that works well here for heating are things such as water, ceramics, certain polymers, etc.\u00a0 These all end up converting microwave energy into heat quite effectively.<br \/>\nMore specifically, Microwave ovens work by having an internal magnetron emit electromagnetic waves around the frequency of 2.45 GHz (vibrates at about 2.45 billion times per second).\u00a0 These waves are absorbed by water molecules, fat molecules, sugars molecules, and certain other substances, which then heat up by a process known as &#8220;dielectric heating&#8221;.\u00a0 Basically, molecules such as water molecules are electric dipoles.\u00a0 This means that they have a positive charge and a negative charge on opposite ends.\u00a0 Thus, they will rotate themselves rapidly when trying to align themselves with the alternating electric field from the microwaves.\u00a0 As these molecules rub against each other, they heat up and, as they do so, they themselves also become part of the cooking process, heating up molecules around them that may not be absorbing much, or any, of the microwaves.<\/p>\n<p><a title=\"origin of the microwave oven\"
