The study suggests the weak but enduring magnetic field ... that over three billion years ago, the moon’s magnetic field was as strong as Earth’s current field, which ranges from 25 to 65 ...

Supernova debris speeds up neutron stars, strengthening magnetic fields. This explains why low-intensity magnetars still produce bursts.

The field often gets very weak, then bounces back, never having flipped. As Ron Merrill, a magnetic-field specialist at the University of Washington remarked when asked whether we're in for a ...

Earth's magnetic poles are shifting unpredictably, with rapid drifts and weakening fields raising questions about a possible future reversal and its global effects.

The dent refers to the weak magnetic field over a particular ... The planet Earth has a strong magnetic field, and this magnetic property comes from its core, which hosts molten iron and nickel.
