The microwaves energy occurs when electric current flows through a conductor. Microwaves are a form of electromagnetic radiation that is very similar to sunlight and radio waves. Trough the test process in a new vacuum tube called a magnetron, the discovery around the candy bar was performed. Dr.Percy Spencer, a self-taught engineer with the Raytheon Corporation has invented this patent. Dr.Spencer fashioned a metal box with an opening into which he fed microwave power. The energy entering the box was unable to escape, thereby creating a higher density electromagnetic field. The conclusion is, when food is placed into the box and microwave energy fed in, the temperature of the food rise very rapidly. Dr. Spencer had invented what was to revolutionize cooking and form the basis of a multimilion dollar industry. Dr.Spencer has invented the microwave oven.
