To demagnetize (degauss) a metal, you can heat it above its Curie temperature and cool it and the magnetic properties will not return. But this is probably not what we're looking for. Degaussing a metal is usually done by "sweeping" it with an alternating magnetic field. That what a degaussing coil does. It's often powered by the 60 cycle per second AC field of the power grid (50 Hertz in lots of places other than the US). Take a coil, include enough windings in it to provide sufficient inductive feedback (so you won't short the line) and you've got a degaussing coil. You may or may not want to include a core. Bulk tape erasers (they're still around) have a core, and TV's with CRT's can be degaussed with a coil that does not have a core built in (it's an air core inductor). The coil (with or without core) has a switch and a power plug. Plug it in, turn it on, and either move the magnet you want to demagnetize around in the field or move the field around the magnet. Slowly move the field away from the (now demagnetized) magnet to decouple it, and turn it off. You've "swept" the magnetic field from the magnet. Tool degaussers work the same way. The duty cycle of degaussers varies, and they come in different sizes and shapes, depending on the application. The heart of the degausser is the AC coil, with or without core. Go to a site like eBay and use "demagnetizer" or "degausser" in your search argument and look at the pictures. Some portable units have a battery to power them up, but the battery will be tied to a circuit that creates AC or pulsating DC (with its "cycling" magnetic field) to provide the degaussing action.
Metal can be demagnetized by subjecting it to a magnetic field that gradually reduces in strength, causing the magnetic domains in the metal to realign randomly and cancel out the magnetization. A demagnetizer is a device that generates such a decreasing magnetic field to demagnetize metal objects by disrupting their magnetic alignment.

What does demagnetize mean?
Demagnetize means to remove the magnetism from an object, causing it to lose its magnetic properties. This can be done by exposing the object to a magnetic field in the opposite direction to cancel out the existing magnetization.
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.
A good way to demagnetize something is to?
De-magnetization refers to the removal of magnetic properties from an object. One way to de-magnetize something is to heat the object.
How do you demagnetize a nail?
To demagnetize a nail, you can subject it to heat by heating it up and then allowing it to cool slowly. Alternatively, you can tap or strike the nail several times with a hammer to disrupt the magnetic alignment of its domains.
How do you demagnetize a apir of tweezers that somehow became magnetized?
One way to demagnetize tweezers is to rub them along a piece of unmagnetized iron or steel in a consistent motion. This can help disrupt and realign the magnetic domains in the tweezers, reducing their magnetization. Another method is to subject the tweezers to rapid heating and cooling cycles, which can also help eliminate the magnetic field.
How do you demagnetize a old pocket watch?
To demagnetize an old pocket watch, you can use a demagnetizer tool specifically designed for this purpose. Simply hold the demagnetizer close to the watch and follow the manufacturer's instructions to remove any magnetic charge that may be affecting the timekeeping of the watch. Be sure to keep the demagnetizer away from any magnetic items like credit cards or electronic devices while in use.
How do you use demagnetize in a sentence?
"It is best to demagnetize metal objects before using them around magnetic tape drives." "Heat tends to demagnetize ferrous minerals."
How do you demagnetize a gold plated chain?
To demagnetize a gold plated chain, you can use a demagnetizing tool like a demagnetizer wand or a demagnetizing machine. Simply pass the tool over the chain several times to remove any magnetic properties it may have picked up. It's important to be gentle and not apply too much pressure to avoid damaging the gold plating.
How do you use a head demagnetizer for a reel to reel tape recorder?
Remove all guards on the deck to expose the tape heads. Plug in and switch on the demagnetizer several feet away from the tape heads. Bring the demagnetizer towards the heads slowly and move back and forth across the play, record and erase heads (it is not necessary to touch them) as well as the capstan and all other metal parts the tape contacts. Move the demagnetizer slowly away and turn it off or unplug only when it is several feet from the heads.
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 can you demagnetize a small object?
You can demagnetize a small object by exposing it to a strong magnetic field in the opposite direction to its current magnetization. Another method is to subject the object to high temperatures, which can disrupt the alignment of the magnetic domains and demagnetize it.
Can you demagnetize a magnet with a magnet?
no you can't
How do you demagnitize something?
You need a "demagnetizer". Some TV repair shops sell a ring that has an electro-magnet in it that you use to fix the colors on a TV when a strong magnetic field messes up the colors. You could "Google" demagnetizer" and look at the results. MCM Electronics sell them too. Cheers!
What are the ways of demagnetize the magnet?
By keeping them in magnet keepers
What did gilligan put in the robot to demagnetize it?
lucky rabbit's foot
Is it impossible to demagnetize steel using iron?
No. Steel is mostly iron.
What one word can you make out of all these letters aeeeidgmntz?
demagnetize
