Magnets melting metal? You’ve got to be joking. Except it is entirely possible, and it looks super cool being done. All you need is an electromagnet and a chunk of metal, and you can see it melt mid air. For this one, they used a 2.6 gram of aluminum as the metal, and an electromagnet using a 1.6 kW power inverter and a frequency of 204 kHz. The temperature goes to 1200 degrees Celsius.
