This is a video of the Yuppiechef demonstrating an induction stovetop, using a pan cut in half. For those of you who aren't familiar with induction cooking, it uses electromagnets to heat things with sorcery. It only works with iron-magnetic materials though, so you can put your hand on it and not feel any heat. Hold on, let me copy/paste something from Wikipedia like this is a high school science report:
In an induction cooker, a coil of copper wire is placed under the cooking pot and an alternating electric current is passed through it. The resulting oscillating magnetic field induces a magnetic flux which repeatedly magnetises the pot, treating it like a lossy magnetic core of a transformer. This produces large eddy currents in the pot, which because of the resistance of the pot, heats it.
For nearly all models of induction cooktops, a cooking vessel must be made of, or contain, a ferromagnetic metal such as cast iron or some stainless steels. However, copper, glass, non magnetic stainless steels, and aluminum vessels can be placed on a ferromagnetic interface disk which functions as a conventional hotplate.
That really didn't make any sense to me and I'm fairly certain that was just a way for "scientists" to try to explain things away with big words when, in reality, the answer is wizards and always has been wizards. Wouldn't it be crazy to find out that all the major inventions in history didn't actually happen through of science, but through wizards who cast spells to make things work? I feel like that's a movie idea. Not a very GOOD movie idea, but throwing money at turds is one thing Hollywood does best.
Keep going for the demonstration AND PREPARE TO BE AMAZED.
