But how does it work then? with the stainless pots?
I took a really strong magnet minutes ago and there was no force at all 
with the stainless
pots. the bottom is very thick on some, but still no force at all.
I remember from stainless bolts and nuts there is some slight attraction, 
but nothing to note
with the pots.

Would these not work with induction? (does one need special pots?)

I thought it needs only be any metal to allow eddy currents to flow, but 
the manuals i have
seen and you say it needs to be iron, which i can believe easily, but then 
the stainless steel
is no more attracted by a magnet than copper ......

why?
