Yes, if you:
-drop it many times
-hammer it many times
-heat it over a flame
Exposure to heat, strong vibrations, or being dropped can cause a magnet to lose its magnetic properties. Additionally, exposure to strong magnetic fields in the opposite direction can demagnetize a magnet.

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.
A magnet can lose its magnetism if exposed to high temperatures. If heated above the point called the Curie temperature, a magnet will lose its magnetism.
No it wont but if the water is hot then it will lose its magnetism
a Temporary Magnet lose its magnetism quickly, a Permanent Magnet is hard and it keeps it magnetism
