Strong magnets tend to be large and power-hungry, but a new design has produced a powerful magnet that fits in the palm of your hand, making it more practical and affordable ...

When we think of powerful magnets used in particle accelerators or for NMR (nuclear magnetic resonance), we often envision bulky machines, sometimes the size of buildings. But in an extraordinary ...

A new study reveals Earth's magnetic flips can last up to 70,000 years, exposing life to increased solar radiation.

A newly developed model defines the upper limit to the strength of planetary magnetic fields. The model can help better understand exoplanets.

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 strength ...

More than a decade of satellite monitoring has mapped Earth’s magnetic field as it subtly altered between 2014 and 2025 — and what scientists have learned is remarkable. The South Atlantic Anomaly, a ...

Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study. Ancient ...

Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes ...

Scientists discover that the Earth's magnetic poles can take up to 70,000 years to reverse, much longer than previously ...
