To demagetize a magnet you could smash one if the ends with a hammer. this will cause the order of atoms to rearange so that it's not magnetic.

How is magnetizing an object the opposite of demagnetizing a magnet?
Demagnetizing. Place the magnet at the opposite end of the metal from where you magnetized it. Again, the magnet must make as much contact with the metal as possible. Rub the metal with the magnet in the opposite direction that you used to magnetize it.
The most efficient method of demagnetizing a magnet is to use an alternating current?
dc with reversing and step-down control
Which type of magnet can easily be magnetized and demagnetized?
An electronic magnet is by far the easiest because you magnetize one by hitting a button (or for home made magnets) connecting a wire, and demagnetizing by hitting the button again or disconnecting the wire.
How could an old magnetic field be preserved in rocks?
Because lava can melt iron (demagnetizing it) and when it solidifies, it will pick up whatever magnet field it is currently subject to, thus locking in a record of the magnet field at the time in history.
How can a magnet lose it's magnetic?
Permanent magnets are magnetic because of things called "domains." Domains are like mini-magnets in the large magnet - when they all line up perfectly, you get a noticeable magnetic field. When they don't, the domains cancel each other out, and hence, do not create a magnet. To demagnetize a permanent magnet, the domains must come out of alignment - this is most easily accomplished by imparting a large force to the magnet (hitting it with a hammer) Alternatively, electromagnets are created via moving charges in a coil of wire (electric current). These magnets are designed to be turned on and off, so demagnetizing an electromagnet is as simple as switching off the current.
If you hit a magnetized nail with a hammer what will happen?
The electrons will fall out of line, demagnetizing the nail.
What is demagnitising current?
Demagnetizing a current means too take away the magnetism from the current ;)
What are the methods of sanitizing and clearing a hard drive?
Degaussing (demagnetizing) Physical Destruction Overwriting
What is the demagnetizing component of armature reaction?
it is the flux which is flowing opposite to the main field flux and demaganetize it... in order to eliminate this demagnetiszing component we have to connect the compensating winding in series with the armature winding which develop the flux in it oppose to the demagnetizing component
What is the advantage of buying magnetic bulletin board?
You don't have to put a hole in your wall. You do however have to risk demagnetizing things nearby. Your choice.
What does a magnet do to a paperclip?
A paperclip attracts a magnet ,a magnet attracts a paperclip.
Why does a mineral magnet stick to a magnet?
a mineral magnet can stick to a magnet because a mineral magnet has to poles the north and the south poles
