There are molecules in a magnet that allow it to stick to other things. It has something to do with positive and negative charges or atoms in an atom cloud, but none of that is important unless you are a scientist. But dropping a magnet could scrape off those important molecules causing it to have less magnetism. It's not that big a difference, but should still be avoided.
A.A permanent magnet works because the individual magnetic fields of the molecules in the material are mostly aligned. It is the net effect of this magnetic alignment that we experience. Dropping a permanent magnet onto a hard surface sends vibrations rippling through the material, thus causing some of the molecules to change position and out of magnetic alignment. A magnet may have to be dropped or hit repeatedly to become completely demagnetized.I suggest that you incinerate it.
Yes, a magnet's magnetism can be destroyed by subjecting it to high temperatures or strong magnetic fields. This can disrupt the alignment of the atoms within the magnet, causing it to lose its magnetic properties.
Permanet Magnet
The known magnetism in a bar magnet is electromagnetism.
A magnet is produced by aligning the magnetic domains in a material to point in the same direction. When heated, the magnet loses its magnetism as the molecular motion, which is caused by heating, destroys the alignment of the magnetic domains. Ferromagnetic materials also lose its magnetism after being melted. However, when the magnet is being hammered whilst cooling in a magnetic field, the melted magnet would gain its magnetism again.
I suggest that you incinerate it.
The same way you destroy anything else. melt it in a furnace is the only way because if you chop it one end will be south and the other will be north If you mean "How do you remove the magnetism from a permanent magnet?" There are several ways. You can heat it past its Curie Point. For iron that is about 800C. Stroking one magnet with another in a random fashion will sometimes work. Hammering it will usually work.
Magnet-ic Magnet-on (also the name of a Pokemon)
Take a strong magnet, and rub it across the weak one and it'll make it stronger. You can weaken or destroy an on objects magnetism with heat or with physical shock such as banging it with something or on something.

Because the magnetism runs from one end of the magnet to the other - across the whole magnet. You cannot have magnetism running in opposing directions in the SAME magnet.
