Induction and copper pans
 

Looking at my instruction booklet for my "Berghoff International (since
1964)" two induction units, I read

"Non-compatible pans:
Heat Resistant Glass, Ceramic container, copper, aluminum pots or pans."


I wonder if some copper pans have a magnetic ring in the bottom to make them
usable on an induction.

The reason I ask is that I have a very-large heavy stainless steel pot
(Kirkland-made in Italy) stock pot [not a part of my regular set, Wayne, if
you are reading] that a magnet does not stick to it, whereas my regular ss
set from Kirkland does have the manget sticking to it.

Thanks for any comment.
