In depends upon how hot you are talking about. Cold would be my best answer in general. If you are comparing the magnetism between say 10 below zero and 100 F then there would be no discernable difference. If you should heat the metal to red-hot, the magnetism would be lost after the metal has cooled.

Does bauxite have magnetism?
No, bauxite does not have magnatism
Would magnets attract to a paperclip under water?
magnets dont lose their magnetism under water. According to me magnets do attract paper under water.
How can a magnet can lose it strength?
Several factors can weaken the magnetism in a magnet such as being stored close to heat, strong electrical currents, other magnets, or radiation. Over time magnet materials lose a very small amount of magnetism.
How would reduce the reverse polarity in magnetization of permanent magnet?
Degauss it and remagnetize it in a field. Best when heated over the magnets Currie point. Cooling it down in a field the reverse of what you started with.
Are magnets metal?
Some magnets are metal. Not all magnets are metal (though I can't offhand think of any magnets that don't at least contain metal), and not all metals are magnets.
What happens to magnets when they are heated?
it will lose its magnetism OR it will get weaker
How magnets loose their property?
Magnets lose their magnetic properties if they are droped down from a height and when they are heated.
Do magnets pull when heated?
A magnet looses its power when heated.
What happens when magnets get heated?
It loses its charged.
Can a magnetic bracelet stop working?
Kinda-sorta, but not really. While magnets can lose some of their power over time, particularly if heated or hit, there's no solid proof that a magnetic bracelet ever has worked. So if the magnets didn't do anything to start with, losing the magnets wouldn't change anything.
Maganets shoud not be heated or hammered Why?
Magnets should not be heated or hammered because it disturbs alignment
Why should magnets never be heated hammered or dropped?
