No.If you break the magnet, it is still a useful magnet.
The oxidation causes magnets to lose protons that are essential for magnetic attraction
they actually do loose their magnetism but it takes about 20 years
You can destroy the magnetism of a magnet by hammering ,heating or using a alternating current method.

Yes.
it will lose its magnetism OR it will get weaker
Yes, because electromagnets can lose their magnetism.
magnets dont lose their magnetism under water. According to me magnets do attract paper under water.
I dont think you can ---- If you super-heat the magnets, it will demagnetize them, thus stopping the "pulling power" of the magnets. Basically stick the magnets in a vat of super boiling water, that should be sufficient enough heat to demagnetize the magnets.
Kinda-sorta, but not really. While magnets can lose some of their power over time, particularly if heated or hit, there's no solid proof that a magnetic bracelet ever has worked. So if the magnets didn't do anything to start with, losing the magnets wouldn't change anything.
