The temperature above which demagnetization occurs is called the Curie
point. This is listed for many materials. For example, it can be as low as
25 deg C for monel (nickel copper alloys) to as high as 1121 C for cobalt.
Nickel-iron alloys are in the range 300-500 C; iron is 770 C.
I think
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?
