A magnet is an object that has a magnetic field. The word magnet comes from the Greek "magnÃtis lÃthos" (μαγνήτης λίθος), which means "magnesian stone". Magnesia is an area in Greece (Now Manisa, Turkey ) where deposits of magnetite have been discovered since antiquity. Permanent magnets can be demagnetized in the following ways: ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ * Heat. Heating a magnet past its Curie point will destroy the long range ordering. * Contact. Stroking one magnet with another in random fashion will demagnetize the magnet being stroked, in some cases; some materials have a very high coercive field and cannot be demagnetized with other permanent magnets. * Hammering and/or Jarring. Such activity will destroy the long range ordering within the magnet. * Being placed in a solenoid which has an alternating current being passed through it. The alternating current will disrupt the long range ordering, in much the same way that direct current can cause ordering. In an electromagnet, ceasing the flow of current will eliminate the magnetic field. However, a slight field may remain in the core material as a result of hysteresis.
What else can I help you with?
Can you demagnetize a magnet with a magnet?
no you can't
What are the ways of demagnetize the magnet?
By keeping them in magnet keepers
Can you demagnetize a magnet and if so, how?
Yes, you can demagnetize a magnet by subjecting it to high temperatures, hammering it, or exposing it to a strong magnetic field in the opposite direction.
How to demagnetize a magnet?
To demagnetize a magnet, you can expose it to high temperatures, pass an alternating current through it, or subject it to strong impacts. These methods disrupt the alignment of the magnetic domains within the magnet, causing it to lose its magnetism.
Will exposing a magnet to a DC magnetic field demagnetize it?
Exposing a magnet to a DC magnetic field typically won't demagnetize it unless the field is very strong and exceeds the coercivity of the magnet. In most cases, a DC magnetic field won't affect the magnet's strength but can alter its orientation or alignment.
How do you demagnatise a magnet?
You can demagnetize a magnet by heating it up to its Curie temperature, by striking it with a hard blow, or by applying an alternating magnetic field that disrupts the alignment of its magnetic domains.
How do you stop a magnet from working?
You can't. You might be able to demagnetize it, but then it's no longer a magnet, it's just a piece of metal.
Which of the following can be done to demagnetize a permanent magnet?
To demagnetize a permanent magnet, you can subject it to high temperatures, apply an alternating current (AC) magnetic field, or strike it with a hammer. These methods disrupt the alignment of magnetic domains within the material, causing the magnetism to be lost.
How can a magnet be stopped?
A magnet can be stopped by exposing it to high temperatures, which can disrupt the alignment of its magnetic domains. Additionally, subjecting a magnet to a strong magnetic field in the opposite direction can also demagnetize it.
How do you magnetize and demagnetize a magnet?
By placing Iron in a strong magnetic field, the field will turn the iron into a magnet. If you melt the iron and then allow it to resolidify, it will drop the magnetic charge (and you can charge it again if you wish).
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 can you demagnetize gold?
Gold is not magnetic, so it cannot be demagnetized. If you are trying to remove any magnetization from a gold object that has been in contact with a magnet, simply separating it from the magnet will be sufficient.
