If a magnet is magnetic on the earth, will it be magnetic on the moon?

Magnets are no longer magnetic on the moon. We all know that the earth can be said to be the most "unique" planet in the entire universe. It is precisely because of the unique conditions of the earth that we humans can sit back and live happily on this peaceful earth, thus creating a great human civilization. Magnets are also a tool that we often use in our daily lives. As we all know, magnets have "magnetic properties" and can play a great role on the earth; but are they still applicable to aliens, such as the moon?

The magnetism inside the magnet is indeed difficult to be affected by external forces. In fact, the strength of magnets is far beyond our imagination. Generally speaking, we can conclude that magnets are suitable in any situation. Friends who have studied junior high school physics may know that magnets also have a so-called critical temperature, which is the "magnet Curie temperature". However, the magnetism of the magnet will not disappear because the Curie temperature of the magnet exceeds the limit. It will only gradually weaken as the temperature increases. But just like the famous paradox, even if the magnet's magnetism disappears , and it will never be possible to have nothing. Unless you use powerful technological means to change the atomic arrangement of the magnet.

But magnetism does not apply to the moon. The main reason why we cannot "wander the earth" and play "space immigration" at will is actually not the survival resources, but the "magnetic field". Planets like the Moon and Mars do not have complete magnetic field systems covering the surface. Mars is better and has a little bit of it; but the moon has no magnetic field at all. Therefore, no matter how strong the magnetic force of a magnet is, it will lose its magnetism on the moon; just like you cannot ask a fish to run fast in the water to run fast when it reaches the shore.

To sum up, although magnets are magnetic on the earth, they are useless on the moon.
