It depends on the type of magnet.
The Curie Point is the point above which a material cannot be a permanent magnet. For iron-type magnets, this is about 770C.
Of course, not all magnets are caused by ferromagnetism. An electric current produces a magnetic field, regardless of the temperature. The earth's core approaches a temperature of 5000 C, but the Earth still has a magnetic field caused by swirling currents in the core of the earth.

How does the magnet works on cold and hot temperature and what important idea.?
the magnet that works better is the cold magnet
What happens if you put a magnet in the refrigerator?
It doesn't do anything. It will still work.
Show bar magnet horse shoe magnet dumb bell magnet etc.?
A dumbbell shaped magnet is called which type of magnet?
What is the difference between horse shoe magnet and U-shaped magnet ped magnet?
between a horse shoe magnet and u shaped magnet?
Why do the magnetic poles move around?
Because the metals in the hot center of our earth are moving arround.
Can a magnet attract to a refrigerator if the magnet is hot?
If it is a magnet, then it can still attract to a refrigerator. If it is a lump of hot metal or hot ceramic, then only gravity will provide attraction. The curie temperature describes when it goes from being a magnet to being a lump.
Is a hot magnet stronger than a cold magnet?
There's no relationship there. But if you take any permanent magnet and heat it hot enough, it loses some or all of its magnetism.
How does the magnet works on cold and hot temperature and what important idea.?
the magnet that works better is the cold magnet
Is the hottest magnet always the best?
no a magnet isn't always at its best when hot. some magnets don't even work when its hot.
What is the reason that a cold magnet is stronger than a hot or room temperature magnet?
A cold magnet attracts more than a hot magnet. This helps the flow of electricity which therefore helps the electric field, which therefore helps the magnetic field. They use cold magnets to power the LHC which collides hydrogen atoms. Obviously the cold magnet is very attracting.
Why is there no black flower in the world?
is a hot magnet shorter or weaker than a cold magnet
Can you attract a hot wheels car with a magnet?
if the hot wheel is metal
Can a magnet attract a hot wheels car?
Try!
Is the strength of a magnet affected by hot or cold temperatures?
NO!!
Whst if a magnet is stronger when hot why would a magnet be stronger when hot why?
more kinetic energy. The hotter the substance the faster the particles are moving and the more heat energy it has
What happens if magnet is heated red hot and cooled?
it will not attract
What should you use to separate a mixture?
a magnet or hot plate
