Watch people in KJ Magnetics cook an egg with some magnets and a motor.
The people at KJ Magnetics, which sells magnets, have found an even more mysterious way to make breakfast. Combining one old motor and a disk of magnets, they were able to use the magnets to generate enough heat to fry an egg in a conductive pan.
The experiment they did at KJ Magnetics was to place a motor on the bottom of a table and on top to place and connect to the motor a small disk. Around the centre of the disk they put ten magnets arranged in such a way that their poles alternated. These magnets are about ten times stronger than a typical refrigerator magnet.
When the magnets spin, their alternating poles cause the magnetic field they produce to constantly change. This produces a type of electricity energy called eddy currents or stream Foucault (eddy current) that flows into the conductive basin and dissipates it energy as heat.
During the first human test at KJ Magnetics, the temperature in the pan reached only 37,7 degrees Celsius, not enough to cook an egg. However, when they almost doubled the strength of the magnets, they were able to raise the temperature to over 100 degrees Celsius and successfully cook an egg.
If all this gave you the idea of making an induction stove for the winter, KJ Magnetics created a guide on how to do it. Watch the video below:
