Residental electrical load [was Re: Who's rewired their house for this hobby?]

Hi Chuck, The lack of heating in your antimagnetic stainless or copper cookware isn't due to a lack of ferromagnetic content - it's a different situation entirely. The issue stems from the electrical properties of the bulk material - in essence, those pots are +too good+ of a conductor at the frequencies in use. The currents flow in a deep, thick layer and encounter trivial resistance. It's this lack of resistance that's responsible for the lack of heat production . I'm sure you've seen the well-known 'magnet down the copper pipe' demonstration, which shows clearly that eddy currents develop just fine in copper - which certainly isn't in the ferromagnetic series. As for glass or ceramic, they're electrical insulators, so there's little to zero current flow at all, and again, no heat production.
