Dear All,
I was thinking about the effect of high temperature on the magnet. I
know that very high temperatures can destroy the magnetic power, but what
about temperatures around 35 or 40ºC, day after day?

John,
Bill is right to query this - a magnet won't attract non-magnetic stainless
steel (by definition!). I think there may be varieties of stainless which
ARE ferromagnetic but the attraction may not be as strong as ordinary steel.
Regards,
John

No, but the magnet is. And a magnet will attract it.
Of course, insead of one piece of steel and one magnet, you could use two
magnets for double the holding strength!
What neat is that the magnet will aslo work at a distance, THROUGH the
glass!
