Removing magnetism from a magnet with electricity?

In summary, the conversation was about removing magnetism from a magnet using electricity. The suggestion was to look for a degaussing coil, which uses a decaying AC magnetic field to demagnetize the material. Searching "degaussing coil" online should provide helpful results.

Hey everyone, wondering if anyone knows if it's possible to remove the magnetism from a magnet through use of electicity. Specifically using 12volts, 2.5 amps DC.

I'm looking for some kind of switch, or converter etc, that would remove the magnetism, but obviously I don't know exactly what I'm looking for.

Any help would be appreciated, thanks =)

The key term you should look for is degaussing coil. That is the most common way to demagnetize stuff. It uses a decaying AC magnetic field to work the B-H curve of the magnetized material back down to the center, so there is no Br left.

Just google "degaussing coil" and you should get some useful hits.

It is possible to demagnetize a magnet using electricity, but it would require a specific type of equipment called a demagnetizer. A demagnetizer uses a strong alternating current to disrupt the magnetic field of the magnet, essentially erasing its magnetism. However, it is not as simple as just using a 12-volt, 2.5-amp DC power source. The power and frequency of the current need to be carefully controlled in order to effectively demagnetize the magnet. It's important to note that this process would permanently remove the magnetism from the magnet, so it may not be suitable for all applications. It's best to consult with a professional or do thorough research before attempting to demagnetize a magnet with electricity.
 

1. How does electricity remove magnetism from a magnet?

Electricity can remove magnetism from a magnet by creating a magnetic field in the opposite direction of the existing magnetization. This causes the magnetic domains within the magnet to become disoriented and cancel out the overall magnetism.

2. Can any type of electricity remove magnetism from a magnet?

No, only direct current (DC) electricity can remove magnetism from a magnet. Alternating current (AC) electricity will not have the same effect.

3. How long does it take for electricity to remove magnetism from a magnet?

The time it takes for electricity to remove magnetism from a magnet depends on the strength of the magnet and the strength of the electrical current being applied. It could take a few seconds to several minutes.

4. Is it safe to remove magnetism from a magnet with electricity?

Yes, it is safe to remove magnetism from a magnet with electricity as long as proper precautions are taken. It is important to use the correct amount of electrical current and to handle the magnet carefully to avoid any potential hazards.

5. Can a magnet be re-magnetized after removing its magnetism with electricity?

Yes, a magnet can be re-magnetized after removing its magnetism with electricity. This is done by exposing the magnet to a strong magnetic field in the desired direction of magnetization.
