German physicists have overcome a long-standing limitation of magnetic field design by outperforming the famed Halbach array with a compact setup that delivers cheaper, stronger, and more uniform ...

MagNav technology measures the Earth’s magnetic fields for navigation as an alternative to jammable GPS navigational signals.

Sometimes, the magnetic fields are relatively weak, like the ones that thread their way through the spiral arms of galaxies. Sometimes, they're medium-strength, like Earth's.

According to the ESA, “Our magnetic field is largely generated by an ocean of superheated, swirling liquid iron that makes up the outer core around 1,864 miles beneath our feet.

Loggerhead turtles “dance” when exposed to food-associated magnetic fields, and their magnetic map may help them return to specific areas after long migrations.

So-called cracks in the Earth's magnetic field have led to spectacular aurora light shows being seen in the skies, despite there not having been a solar storm to generate them.. According to ...

The sun’s powerful magnetic field has long puzzled scientists. A new study suggests the source of its magnetic field is nearer the surface than first thought.
