Description: en.wikipedia.org/wiki/Induction_heating en.wikipedia.org/wiki/Induction_cooking I found that after more than 2 years, no one repeated the experiment more effectively, although there were attempts. But the video continues to interest people, so I revised it with details. Asynchronous motor 180 W, 50 Hz, 1380 RPM. I raised the frequency to 145 Hz to increase RPM to 4000 RPM. With a further increase in the frequency, the RPM begins to fall, since the magnets slow down the rotation. For this, only a more powerful engine will help. Neodymium magnets 20X3 mm, 60 pieces (6X10). The volume of water is about 25 ml. If you will be using a powerful motor, be sure to center the disc and magnets precisely to eliminate vibration. And observe safety measures, fix the magnets carefully and step back to a safe distance.
