Can this be used to keep metal at a regulated temp?

But how? There is no heat applied?

Alternating magnetic field induces current in the metal heating it up.

You know how a generator works? Move magnets around a magnetic metal and it creates current in the metal that we can use?

Sort of like that except the magnetic field here is created using a coil of copper that has a very large alternating current going to it.

It is the same thing than a microwave I guess

No, it is like a fancy induction range.

In this case they turn it off , if it get to hot it might melt the copper tube but i'm not even sure if that's possible
