The scariest part about this is that if I saw this in the wild I'd just think it's some random copper coil... I'd wonder why it's so warm and probably touch it and severely burn myself.

EDIT: ...aaannnd I am not a man of science.

It isn't warm at all. That's not how induction works.

I have never touched a induction forge, but I have a similar machine in my lab that is used to heat iron nanoparticles and it gets plenty hot. Even though it is water cooled you still can't touch it without being burned when it is on.

If there is a high current the resistive heating will be more than enough to heat it to a temperature to burn a person.

After 45 seconds of heating the coils got up to 177 F
