high temperature, AC magnetic fields, mechanical shocks, and physical distortion.
If you heat a magnet, it looses its magnetism.
The known magnetism in a bar magnet is electromagnetism.

Magnetism is the number of magnetic moments per unit of volume. It is the volume of the magnet which determines the magnetism. If an object has great weight and great volume, it will be a strong magnet. If an object has great weight but lesser volume, the magnetism will be weaker.
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.
The force is called "magnetism". The refrigerator is not magnetic, but the magnet will temporarily induce magnetism in the refrigerator's metal - the part that is close to the magnet.
Yes, if you: -drop it many times -hammer it many times -heat it over a flame

It would last longer in cold weather because heating causes a magnet to lose its magnetism.

A magnets magnetism is strongest at the poles.
No it wont but if the water is hot then it will lose its magnetism

Some words with the root "magnet" include magnetism, magnetic, and magnetize.
