A magnet is an alignment of particles in a solid. You can imagine a magnet as a bunch of tiny magnets that are all pointing in the same direction. When they point in the same direction, the little parts add up, and the magnet works like you'd expect.

When you heat or hammer a magnet, the little magnetic parts can get jostled and unaligned. When that alignment is disturbed, they no longer point in the same direction and may even cancel other magnetic parts out, weakening and eventualy destroying the magnetism.

Why does a magnet lose its' magnetism by hammering and heating?

When a magnet is hammered or heated, it disrupts the alignment of its magnetic domains, causing them to become disordered. This disorderliness reduces the overall magnetic field strength of the magnet, resulting in a loss of magnetism.


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.


How to cause a magnet to lost its magnetic power?

A magnet can lose its magnetism if exposed to high temperatures. If heated above the point called the Curie temperature, a magnet will lose its magnetism.


What happens if you hit a magnet?

Hitting a magnet may affect its magnetic domains and thus may remove its internal magnetism, thus the magantism may be reduced or even removed by hitting it.


Does color affect magnetic force?

Color does not affect magnetic force. But as magnet gets heated it loses magnetism


Why does a magnet lose its magnetic property when it is hammered?

Hammering a magnet causes the magnetic domains within the material to become misaligned, disrupting the overall magnetic field. This results in the magnet losing its magnetic property because the alignment of the domains is what creates the magnetism.


What mineral is a magnet?

Lodestone, a variety of the mineral magnetite, displays strong magnetism. Some other minerals are weakly magnetic, or display magnetism when heated.


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.

Why does a super cooled magnet conduct a bigger magnetic field than a normally heated magnet?

Per se - it doesn't. The reason to use a supercooled magnet is that the power consumption is much lower, so its a question of economics - not magnetism.


What do you understand by demagnetization?

De-magnetism is when a magnet is no longer a magnet. For example, when a magnet becomes heated it loses its magnetism. This is because the alignment of domains (groups of atoms) is disrupted. This is due to the expansion of the domains; the energy to expand is provided from the heat. During the expansion, the domains require more space therefore disrupting the alignment. This causes a magnet to become weaker and weaker to the point where it is no longer a magnet.... Hope this helps! :)
