Sort of. Magnets become weaker with heat, but boiling water is not enough to completely demagnetize unless it was a very weak magnet to begin with. It will become weaker, but the only fool-proof way is to make it borderline molten, completely randomizing the domains.

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.
What happens when you mix ice water and saturated water?
Saturated water is water that's passed its boiling point yet hasn't evaporated yet. When putting ice water within this boiling-hot water, the heat energy from the boiling water transfers rapidly into the ice water, mixing the two and rapidly changing temperatures.
Why do hot beakers crack in cold wale?
im assuming you meant to type water... this happens because heat makes things expand, whilst cold makes things contract. by putting a hot beaker in cold water, you put too much strain on the beaker because it is changing size so fast
Is it better to wash clothes in hot or cold water?
Hot water.
What kills germs faster cold or hot water?
hot water
Does putting a magnet in the water for 60 minutes make the magnet lose its magnetism?
No it wont but if the water is hot then it will lose its magnetism
Why does a magnet get stroger in cold water but weaker in hot water?
Because it loses it's strengths in hot water and gains strength in cold water.
Can you die from putting a bleeding cut under hot water?
No, you cannot die from putting a bleeding cut under hot water. The only bad thing about putting a bleeding cut under hot water is that it expands the vessels and will not stop the bleeding. Luke warm water or cold water is the best for a bleeding cut.
How do you get a chip out of a stone bench?
by putting hot water on
How do you clean kitchen tool and equipment?
by putting hot water
What happens if you put a magnet in the refrigerator?
It doesn't do anything. It will still work.
How does putting hot water into a fridge to cool it waste electricity?
The hot water warms the refrigerator, which forces it to turn on to cool it off.
How can you determine a coin is not pure silver?
By putting it in hot water for a week
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.
What equipment used to separate salt water of the mixture magnet balance funnel or hot plate?
I believe it is a hotplate
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
