Rare earth metals power modern tech and clean energy, driving global trade shifts and geopolitical tension as new materials ...

If a strong magnet comes close, it can scramble the arrangement of these particles, essentially "erasing" the data. Again, everyday magnets are not strong enough to wreak that kind of damage.

Many of those lunar samples show signs of exposure to strong magnetic fields comparable to Earth's, yet the Moon doesn't have such a field today. So, how did the moon rocks get their magnetism?
