Melting steel with copper tubing: When a strong electric current runs through the copper, it acts as an electromagnet, holding the steel slug aloft. Then the electrical resistance of the steel converts part of the electrical energy into heat. Quiet a lot of heat.

Damn +Dustin Wyatt – Are you wearing safety gear while doing this? How much current is going through there?
COUNTER CLOCKWISE ROTATION. COPPER IS A CONDUCTOR , WONDER WHAT WOULD HAPPEN IF YOU USED A MORE CONDUCTIVE MATERIAL Â , GREAT INDUSTERIAL APPLICATIONS.
That's pretty amazing… have to try that sometime 😀
