There are only a few factors that can affect the stability of the Earth's Magnetism. This extraordinary magnetism is influenced by elements such as time, temperature, and several other things, but even these elements do not have a large impact on Rare Earths.
The following paragraphs explore six things that can affect the stability of these magnets, and these are time, temperature, change of aversion, exposure to adverse fields, radiation, and improper handling.

The effect that time has on magnets is minimal, but can still be seen. Because the effect is relatively small, it is often referred to as magnetic creep. Over 100,000 hours, the creep will cause Rare Magnet to lose about three percent. 100,000 is equal to around 4,167 days or eleven years, and during that period, a three percent loss was very small.
Temperature can also have an effect on the Earth's Magnetism. If a magnet is used at a temperature above its Curie temperature, its ability to draw will decrease. When it is above the Curie's temperature, it becomes paramagnetic. When it becomes paramagnetic, the magnetic moment occurs in a state that is completely irregular. However, even at temperatures that are too low, its ability can also be reduced.
Magnetic resistance is also referred to as aversion, and in some cases, Rare Magnets can experience changes in their reluctance. This only happens after the magnet undergoes permanent changes. These changes can include changes in the dimensions of the air gap when the magnet is operated.
