A magnet obtains its properties by aligning the molecules, or at least the magnetic domains of them.
When heated, the magnetic domains, in common with the other molecular properties, become more randomized, and point variously.

∙ 13y agoHeating a magnet can remove it's magnetism as the particles (domains) get excited and start forming a nonmagnetic arrangements.
This is wrong. Whoever wrote it is totally inaccurate. Sorry I don't know the answer, but I would advise you to just Google it again and not rely on people like that who answer with crap.

What are three ways to destroy the magnetism of a magnet?
I suggest that you incinerate it.
How can magnetism be destroyed?
---- Magnetism can be destroyed by following methods:---- * By heating the magnet, * By hammering the magnet.--->In accordance to this point...allowing the magnet to fall violently* By keeping similar poles of magnets together for a long time. * [not sure about this]by keeping magnet under running water.
Will a magnet still be a magnet if it is melted?
A magnet is produced by aligning the magnetic domains in a material to point in the same direction. When heated, the magnet loses its magnetism as the molecular motion, which is caused by heating, destroys the alignment of the magnetic domains. Ferromagnetic materials also lose its magnetism after being melted. However, when the magnet is being hammered whilst cooling in a magnetic field, the melted magnet would gain its magnetism again.
Can a magnet's magnetism be destroyed?
A magnet can be demagnetized by striking it many times, heating it, or cooling it. All of these randomize the domains.
What type of magnetism is present in a bar magnet?
The known magnetism in a bar magnet is electromagnetism.
Can a magnet lose its magnetism by heating?
Yes
How could heating a bar magnet reduce its magnetism?
Heating a bar magnet could reduce its magnetism because the heat, by raising the energy level in the metal, disorients the atoms, which disrupts the magnetism.
How can a permanent magnet become a nonmagnetic?
By heating it beyond its Curie point will remove all magnetic properties, hammering or jarring it will also remove most of the magnetism.
Why does a magnet lose its' magnetism by hammering and heating?
The magnets' domains become unaligned.
What does heating a magnet do?
Nothing up to some critical temp (around 600 degrees I believe), after which the "magnet" looses its magnetism.

Would a magnet to last longer in hot or cold weather?
It would last longer in cold weather because heating causes a magnet to lose its magnetism.
Heating or hitting a perminant magnent can ruin it?
yes any magnet either heated or hit hard loses its magnetism
Will magnets lose it's power by rubbing?
You can destroy the magnetism of a magnet by hammering ,heating or using a alternating current method.
Can a magnet's magnetism be destroyed?
A magnet can be demagnetized by striking it many times, heating it, or cooling it. All of these randomize the domains.
