The result was the egg exploding in the face of one of his co-workers, who was looking in the kettle to observe. Spencer then created the first true microwave oven by attaching a high-density electromagnetic field generator to an enclosed metal box. The magnetron emitted microwaves into the metal box blocking any escape and allowing for ...
In 1947, just a year after Spencer’s snack food serendipity, the first commercial microwave oven hit the market. Called the “Radarange,” it weighed nearly 750 pounds and cost more than $2,000 .
A microwave oven with a turntable. A microwave oven cooks or heats food by dielectric heating. Cooking food with microwaves was discovered by Percy Spencer on October 8, 1945, while building magnetrons for radar sets at Raytheon. Spencer was working on an active radar set when he noticed a strange sensation, and saw that a peanut candy bar he ...
A microwave oven or simply microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. [1] This induces polar molecules in the food to vibrate [2] and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently ...

Over time, ovens have become more high-tech in terms of cooking strategy. The microwave as a cooking tool was discovered by Percy Spencer in 1946, and with help from engineers, the microwave oven was patented. [12] The microwave oven uses microwave radiation to excite water molecules in food, causing friction and thus producing heat. [13]
