In an Earth-sized take on the age-old ‘correlation or causality’ question, researchers have come across a fascinating match between Earth’s magnetic field and its oxygen levels si… ...

Earth’s oxygenated atmosphere and magnetic field make life possible, but scientists have discovered that there’s a hidden link between the two that’s stronger than we originally imagined.

Earth's magnetic field and oxygen levels have increased more or less in parallel over the past 540 million years, suggesting the two factors are linked in some way, researchers say.

Scientists have demonstrated a new recording principle that improves recording efficiency by 35% by combining spin torque with conventional heat-assisted magnetic recording (HAMR).

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform ...

Researchers at Tohoku University have achieved a significant advancement in opto-magnetic technology, observing an opto-magnetic torque approximately five times more efficient than in conventional ...

The field is getting weaker in Canada but stronger around Siberia, and “that pulls the magnetic pole towards Siberia,” Beggan tells Kasha Patel of the Washington Post.

Unlike the geographic North Pole, which marks a fixed location, the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion.

Every so often, Earth's magnetic poles completely flip. What causes this to happen? And how do these reversals affect life on Earth?
