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.
What else can I help you with?
How does the magnet works on cold and hot temperature and what important idea.?
The strength of a magnet can be affected by temperature. In cold temperatures, a magnet's strength increases, while in hot temperatures, the strength decreases. This is because temperature affects the alignment of atoms within the magnet, which in turn affects the magnet's ability to produce a magnetic field. An important idea to note is that extreme temperatures can demagnetize a magnet altogether.
What happens if you put a magnet in the refrigerator?
A magnet will stick to the metal surface inside the refrigerator. It will not damage the refrigerator or affect its operation in any way. The cold temperature of the refrigerator may slightly weaken the magnet's strength, but it will still function normally once removed.
What happens to the bar magnet as it nears the U magnet the bar magnet will?
Move towards the U magnet so that the poles attach.
A magnet made of a material that keeps its magnetism is called?
Permanet Magnet
Show bar magnet horse shoe magnet dumb bell magnet etc.?
I'm unable to display images, but I can describe them for you. A bar magnet is a straight magnet with north and south poles at opposite ends. A horseshoe magnet is shaped like a horseshoe, with both poles located at the ends of the curved section. A dumbbell magnet consists of two bar magnets joined at the center. Each magnet has its north pole connected to the south pole of the other magnet, creating a closed loop magnetic field.
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 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.
Can you attract a hot wheels car with a magnet?
if the hot wheel is metal
Why is there no black flower in the world?
is a hot magnet shorter or weaker than a cold magnet
Can a magnet attract a hot wheels car?
Try!

Is a hot magnet stronger than a cold magnet?
A hot magnet's strength typically decreases as it heats up because heat disrupts the alignment of its magnetic domains. In contrast, a cold magnet usually has stronger magnetic properties because the lower temperature helps maintain domain alignment.
What should you use to separate a mixture?
a magnet or hot plate
What happens if magnet is heated red hot and cooled?
it will not attract
What is operation process for hot plate with magnetic stirrer?
This particular hot plate is a common piece of laboratory equipment used for mixing solutions in the laboratory. It has a slow spinning magnetic field generated in the hot plate and this spins a plastic coated magnet placed inside the solution being heated. Turn the hot plate on, place the beaker with the solution on the hot plate. Place the magnet in the solution, adjust the temperature and speed of the magnet with dials on the front of the hot plate. This hot plate does not get hot enough usually for cooking.
What kind of magnet is in revs up hot wheels?
A small one
