The strongest man-made magnet in the world is the 45 tesla hybrid magnet at the National High Magnetic Field Laboratory in Florida, USA. It combines a resistive magnet with a superconducting magnet to achieve its record-breaking magnetic field strength.
A magnet can become demagnetized by exposure to high temperatures, strong magnetic fields, or physical impacts that disrupt the alignment of its magnetic domains. These factors can cause the magnetic domains to lose alignment, weakening or eliminating the magnet's magnetic field.

Yes, you can demagnetize a magnet by subjecting it to high temperatures, hammering it, or exposing it to a strong magnetic field in the opposite direction.
To demagnetize a magnet, you can expose it to high temperatures, pass an alternating current through it, or subject it to strong impacts. These methods disrupt the alignment of the magnetic domains within the magnet, causing it to lose its magnetism.
Exposing a magnet to a DC magnetic field typically won't demagnetize it unless the field is very strong and exceeds the coercivity of the magnet. In most cases, a DC magnetic field won't affect the magnet's strength but can alter its orientation or alignment.
You can demagnetize a magnet by heating it up to its Curie temperature, by striking it with a hard blow, or by applying an alternating magnetic field that disrupts the alignment of its magnetic domains.
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.
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 magnet can be stopped by exposing it to high temperatures, which can disrupt the alignment of its magnetic domains. Additionally, subjecting a magnet to a strong magnetic field in the opposite direction can also demagnetize it.
To magnetize a magnet, it needs to be exposed to a strong magnetic field. This can be achieved by rubbing it against a stronger magnet or by subjecting it to an electric current. To demagnetize a magnet, you can heat it to a high temperature, subject it to strong vibrations, or expose it to a demagnetizing field.
Factors that can weaken a magnet include exposure to high temperatures, physical damage like dropping or hitting the magnet, and exposure to strong magnetic fields in the opposite direction.
Gold is not magnetic, so it cannot be demagnetized. If you are trying to remove any magnetization from a gold object that has been in contact with a magnet, simply separating it from the magnet will be sufficient.
