Will exposing a magnet to a DC magnetic field demagnetize it?
Obviously no.
How do you demagnatise a magnet?
You can demagnetize a magnet by: -dropping it many times -heating it over a flame -hammering it many times
What happens when you hammer a magnetised nail?
It makes all the domains of the magnet jumble up ( they all turn separate ways ) So the nail is no longer acting as a magnet
What happens to a magnet force when a bar magnet is cracked through the middle?
If a bar magnet is broken in half, each half is a magnet with its own north and south pole. The force used to break the magnet will also tend to partially demagnetize the magnet, although that might be a minor effect.
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 are the ways of demagnetize the magnet?
By keeping them in magnet keepers
Can you demagnetize a magnet with a magnet?
no you can't
Which of the following can be done to demagnetize a permanent magnet?
heating the magnet past the Curie point
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.
Will exposing a magnet to a DC magnetic field demagnetize it?
Obviously no.
How do you demagnetize a gold plated chain?
Let it sit on a magnet overnite
How do you demagnatise a magnet?

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.

How you can demagnetize materials?
A magnet has magnetic properties because the dipoles of the atoms are lined up in a single direction. To demagnetize it, you must scramble the dipoles out of alignment. First, heat the magnet past the Curie point (the temperature at which it loses its magnetic properties until cooled). Strike it on the ends of the magnet with a hammer. When cooled, it will no longer be magnetized.
