Technical accuracy

I think my introduction is correct, but someone double check for me. --Robert W King 12:46, 28 March 2008 (CDT)

Robert, if your email question to me was about this article, the nuclear magnetism is not the issue. This would appear to work by inducing eddy currents in the electron clouds. I will look for more information for you. David E. Volk 13:07, 28 March 2008 (CDT)
No, that was a seperate question. --Robert W King 13:10, 28 March 2008 (CDT)

Robert, see this link: http://www.inductionatmospheres.com/induction_heating.html

Basically, in a conductor, the changing magnetic field induces current, and due to electrical resistance of the conductor, heat is generated. I believe they use this technique for hardening steel, for example. David E. Volk 13:14, 28 March 2008 (CDT)

The plain old resistanc to electrical current is one mechanism (and the main one). A secondary mechanism comes from magnetic hysteresis (i.e. the tendency of some magnetic materials to resist changes in the magnetic field). This link:
