Demagnetization of repelling poles

[Hypochondriac]

Bit of a simple question but one I've never really had to think about.

Lets say you have two opposing poles of a magnet (a ferromagnet i guess), they repel of course, but will forcing them to stay next to each other eventually demagnetize them?
My instinct tells me no, but maybe the force generated could disorganise the manetic dipoles in the ferromagnet?

Interesting question, conventionally to destroy the dipoles in a magnet, sufficient heat past its Curie point and impact of the material will disable the magnetic capabilities. Try doing a simple experiment first, magnetize an iron nail, then repel the like poles with a permanent magnet. However, I do agree with your intuition that it will not disorganize the dipole. It will most probably require a huge amount of opposing magnetic force (i.e. electromagnetic pulse in the opposing direction.)

I can assure you that forcing two opposing poles of a magnet to stay next to each other will not demagnetize them. This is because the magnetic field of a magnet is created by aligned magnetic dipoles within the material. When two magnets are placed close to each other with opposing poles, the magnetic dipoles within each magnet will still remain aligned and therefore maintain their magnetic properties.

The force generated between the two magnets may cause some slight disorganization of the magnetic dipoles, but this will not be enough to completely demagnetize the magnets. In order to fully demagnetize a magnet, a much stronger external magnetic field or high temperatures are required to disrupt the alignment of the magnetic dipoles.

In fact, the repelling force between the two magnets may even help to strengthen their magnetization, as it is a natural property of magnets to align their dipoles in the same direction to minimize repulsive forces.

So, in conclusion, forcing two opposing poles of a magnet to stay next to each other will not demagnetize them. The magnetic dipoles within the magnets will remain aligned and their magnetic properties will be maintained.
