How can a permanent magnet be demagnetized effectively?
A permanent magnet can be demagnetized effectively by subjecting it to high temperatures or strong magnetic fields in the opposite direction of its magnetization. This disrupts the alignment of its magnetic domains, causing it to lose its magnetism.
How can a permanent magnet be demagnetized?
A permanent magnet can be demagnetized by exposing it to a strong external magnetic field in the opposite direction of its original magnetization, heating it above its Curie temperature, or subjecting it to physical impacts that disrupt its magnetic alignment.
How can a permanent magnet be demagnetized?
A permanent magnet can be demagnetized by subjecting it to high temperatures, strong magnetic fields in the opposite direction, or physical shock. These methods disrupt the alignment of the magnetic domains within the material, causing it to lose its magnetism.
What is a temporary magnet called?
A temporary magnet is called a soft magnet. It can be easily magnetized and demagnetized, unlike a permanent magnet that retains its magnetism for a longer period of time.
How long does it take for a magnet to lose its power and become demagnetized?
The time it takes for a magnet to lose its power and become demagnetized depends on factors like the material of the magnet and how it is used. In general, permanent magnets can retain their magnetism for a long time, even decades or centuries. However, external factors like high temperatures, strong magnetic fields, or physical damage can cause a magnet to lose its power more quickly.
What will happen to the magnet if you put some electricity on it?
it will be demagnetized

How can a magnet become demagnetized?
A magnet can become demagnetized by exposure to high temperatures, strong magnetic fields, or physical impacts that disrupt the alignment of its magnetic domains. These factors can cause the magnetic domains to lose alignment, weakening or eliminating the magnet's magnetic field.
Can a magnet attract to a demagnetized iron rod?
Yes. In this case, the magnet will induce magnetism in the iron, which is originally unmagnetized. Once the magnet is removed, the iron may return to an unmagnetized state; unless the magnetic field near the piece of iron is very strong.
How can iron be demagnetized?
an iron can be demagnetised by ;-hammering it while facing east _west direction -hitting it hard on the ground -connecting it into an ac current while facing the east _west direction .

However, external factors like high temperatures, strong magnetic fields, or physical damage can cause a magnet to lose its power more quickly.
What is the thing that weakens a magnet?
Magnets are "demagnetized" by extreme heat. If you boil a magnet in water, the heat will demagnetize the magnet.
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.
Can objects be demagnetized?
yes, an object can be demagnetized by 3 ways:hammeringheatingalternating current method
