Three effective ways to demagnetize a magnet include heating it, striking it, and exposing it to an alternating magnetic field. Heating causes the thermal agitation of atoms, disrupting the magnetic alignment. Striking the magnet can break the alignment of magnetic domains, while an alternating magnetic field gradually reduces the magnetism by reversing the direction of the magnetic domains. Each method can effectively reduce or eliminate a magnet's magnetic properties.
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.
By placing Iron in a strong magnetic field, the field will turn the iron into a magnet. If you melt the iron and then allow it to resolidify, it will drop the magnetic charge (and you can charge it again if you wish).
Cutting a magnet in half can be done in a number of ways. A hack saw might work well (but the cuttings will stick to the magnet and the saw blade). Some magnets can actually be broken in half. But that leaves a "rough" end and is imprecise.
To partially or completely demagnetize a magnet, you can expose it to high temperatures, strike it with a hammer, or subject it to an alternating magnetic field. Over time, a magnet's strength naturally diminishes as its magnetic domains become misaligned.

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.

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.

Magnets are "demagnetized" by extreme heat. If you boil a magnet in water, the heat will demagnetize the magnet.
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.
