a permanent magnet has its domains arranged in one direction at all times and is thus able to exercise magnetic properties at all times, but it loses its magnetism if it is heated to a certain extent
second way is to hammer it constantly. this disrupts the alignment of the domains (i.e. they are originally aligned in the same direction) and causes them to align in different directions thus destroying the magnetic behavior of the magnetic.
If their microcrystalline structure or chemical composition change, they tend to no longer be magnetic.
Permanent magnets can lose their magnetism if the material they are made from is exposed to high temperatures or strong magnetic fields that disrupt their alignment of magnetic domains. They can also lose their magnetism if physically damaged or if they are demagnetized intentionally using special techniques.

Is iron a permanent magnet?
No, iron is not a permanent magnet. It can be magnetized in the presence of a magnetic field but will lose its magnetism once the external magnetic field is removed. Permanent magnets, on the other hand, retain their magnetism without the need for an external magnetic field.
A magnet made of a material that keeps its magnetism is called?
Permanet Magnet
Is a bar magnet a permanent magnet?
A permanent magnet is a magnet which will keep its magnetism for a very long time and is difficult to change. No, As I think a permanent magnet means they have abilities to hold the magnetism when they are magnetized. Such as Alnico permanent magnets, but in fact, they can be demagnetized,such as high temperature, hit each other,pulse waves, out magnetic field influence...What's more, different permanent magnetic material, have different abilities on holding magnetism,they can be used in different environments. you can find some details from some manufacturers website, to learn some knowledges.
What type of magnetism is present in a bar magnet?
A bar magnet exhibits ferromagnetism, which is the strongest type of magnetism. It is characterized by the alignment of magnetic moments within the material, creating a strong magnetic field.
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.
What is the difference between permanent pole and temporary pole?
a Temporary Magnet lose its magnetism quickly, a Permanent Magnet is hard and it keeps it magnetism
What kind of magnet is strong and will not lose its magnetism unless damaged?
Something called a permanent magnet
A permanent magnet will lose magnetism?
Under some conditions, sure. Impact and intense heat for instance can render a magnet weaker.
What happens when you touch a piece of iron to a permanent magnet?
When you touch a piece of iron to a permanent magnet, the iron can become magnetized temporarily because it can align its domains with the magnetic field. However, once the iron is removed from the magnet, it will lose its magnetism over time. The iron itself does not retain a permanent magnetism like the original magnet.
What is the difference between a permanent magnet and a temporary magnet?
Temporary magnet: good example is an electromagnet. It maintains magnetic attraction only so long as an electric current surrounds it. Permanent magnet: most common. Example: bar magnet. Will maintain magnetic properties for quite a while, although they can be eventually demagnetized.
Is iron a permanent magnet?
No, iron is not a permanent magnet. It can be magnetized in the presence of a magnetic field but will lose its magnetism once the external magnetic field is removed. Permanent magnets, on the other hand, retain their magnetism without the need for an external magnetic field.
Permanent and temporary magnets?
Permanent magnets are materials that retain their magnetism once magnetized, such as iron or neodymium magnets. Temporary magnets, like soft iron, only exhibit magnetism when in the presence of a magnetic field; they lose their magnetism once the field is removed.
A magnet made of a material that keeps its magnetism is called?
Permanet Magnet
Does putting a magnet in the water for 60 minutes make the magnet lose its magnetism?
No, placing a magnet in water for 60 minutes should not cause it to lose its magnetism. Magnets do not lose their magnetism by simply being submerged in water for a short period of time.
Is the magnet in a compass a permanent or electromagnet?
The magnet in a compass is a permanent magnet. It retains its magnetism without the need for an external electrical current.
How is a permanet magnet destroyed?
Physical damage, exposure to extreme heat, or exposure to strong magnetic fields can cause a permanent magnet to lose its magnetism. Once a permanent magnet is demagnetized, it is very difficult to restore its original magnetic properties.
How does a permanent magnet loses its magnetism?
It can lose it by being heated, being struck or being exposed to a rapidly changing magnetic field.
