Re: [Phys-L] Lenz's law and conservation of energy

You can heat materials using induced currents.
You can levitate materials using induced currents.  

With a little cleverness, you can do both at once, thereby melting metals without any container!

The stove top is ceramic w/ the RF coil imbedded.  Yes?


Ohms / inch ?!

Give relative efficacy of various metals and frequency, etc.:
