This guy makes a very interesting coil that could be made at home with a few parts. It doesn’t take a scientist or physics student to make one of these its pretty easy. Here is how this home experimenter describes this device:
In this video, I make a pancake coil for inductive heating the surface of parts that wouldn’t make sense to build a regular coil for. It can also be used for cooking. Induction cooktops are more efficient than a gas or electric stove because there is less wasted heat.
NOTE: DO NOT TRY THIS WITHOUT THE SUPERVISION OF A PROFESSIONAL
It is called a pancake coil for the obvious reason that the shape and color somewhat resemble one 😉
Let’s watch this thing heat up in the video on page 2
