This persnickety number determines the strength of magnetic fields. It figures in everything from motors and generators to audio speakers. Oh, and without it we’d live in eternal darkness.

Space is full of radiation. So much radiation, in fact, that the only thing standing between us and our planet being bathed in radioactive energy from the Sun is the Earth's magnetic field. And this ...

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...

Event Horizon Telescope data reveal the magnetic field around M87* shifted, weakened and then flipped, defying theoretical expectations.

Primordial magnetic fields, billions of times weaker than a fridge magnet, may have left lasting imprints on the Universe.

New research reveals that faint magnetic fields from the early Universe helped shape the cosmic web. These ancient fields ...

The iron-rich core at the centre of our planet has been a crucial part of Earth’s evolution. The core not only powers the ...

Long before galaxies sparkled in the sky or stars took shape, invisible forces stirred in the early Universe. One of those ...

For desert ants, Earth’s magnetic field isn’t just a compass: It may also sculpt their brains. Stepping outside their nest for the first time, young ants need to learn how to forage. The ants train ...

Recently, I came across a piece of news stating that scientists have discovered that the Earth's magnetic field is declining, which really startled me. I mean, if this magnetic field keeps decreasing, ...

Tens of thousands of years ago, the Earth’s magnetic field flipped — and now, scientists have recreated the haunting sound it made during that cataclysmic event. Using data from the European Space ...
