The Earth’s magnetic field, a silent guardian against harmful solar radiation, has been behaving strangely in recent years.

The reason magnetic fields are so important is that they can shield a planet from solar wind and ionizing particles. Mars could get one through Phobos.

Unlike the Earth, Mars does not have a strong, global magnetic field. This field helps to protect our planet from cosmic rays and retain its atmosphere.

The Earth’s geomagnetic field, which scientists have been warning about for hundreds of years, isn’t about to suddenly flip over after all, according to a new study. It now looks like the ...

Their investigation connects a magnetic field reversal about 42,000 years ago to climate upheaval on a global scale, which caused extinctions and reshaped human behavior.

For decades, scientists have puzzled over why lunar rocks show signs of strong magnetism when the moon itself has no global magnetic field today. New simulations suggest the answer may lie in a ...

New research suggests that the largest magnetic fields in the universe originated through some exotic mechanism that absolutely soaked the early cosmos.
