-- Stick it in a gas flame and heat it to glowing.
-- Drop it on the floor or hit it with a hammer a few times.
-- Stick it into a DC-current-carrying coil of wire for a while, in the direction opposite
to the way the poles appear when you do the same with an unmagnetized piece
of iron.
-- Stick it into an AC-current-carrying coil of wire for a shorter while, in either direction.

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 are three types of metal that can be turned into a permanent magnet?
There are two main/most common, types of magnet. One is permanent and the other is temporary. There could be more detailed classifications, but I do not know them ;)
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.
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
Which of the following can be done to demagnetize a permanent magnet?
heating the magnet past the Curie point
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
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?
You can demagnetize a magnet by: -dropping it many times -heating it over a flame -hammering it many times
What is used to make magnets?
A good permanent magnet should produce a high magnetic field with a low mass, and should be stable against the influences which would demagnetize it. The desirable properties of such magnets are typically stated in terms of the remanence and coercivity of the magnet materials.
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.
Is the magnet in a compass a permanent magnet or electronic?
A. Compasses typically use a permanent magnet.
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.
Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
