Not 100% on this though. I have heard that magnetic force lasts about 400 years unless magnetized again. Not 100% on this though.

The magnetism is created by placing the hematite in a strong magnetic field. This induced magnetism will last longer if a) you don't drop it b) you don't heat it up c) you don't put it near another magnet I’ve had one for about five years – it’s still magnetised.

One way to think about it is that the process of magentization aligns the iron particles in the stone so that they are oriented the same direction (with their individual north south poles lined up). It isn't like charging a battery. Unless something happens to scramble the particles back up, the magnetization will stay.
