A recent study published inScience Advances reveals that a temporary collapse of Earth’s magnetic field, known as the ...

It’s something [mircemk] demonstrates, with an Arduino-powered magnetic field strength meter that uses a UGN 3503U Hall effect device. The circuit is extremely simple, comprising the sensor, an ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could ...

A new study reveals that magnetic fields in the early universe were likely billions of times weaker than those of a small ...

When Our Magnetic Field Flips By Rick Groleau Posted 11.18.03 NOVA Every so often—every 250,000 years on average—the Earth's magnetic poles reverse polarity. If such a reversal happened today ...

The magnetic fields that formed in the very early stages of the universe may have been billions of times weaker than a small ...

New research suggests that the largest magnetic fields in the universe originated through some exotic mechanism that absolutely soaked the early cosmos.

Will migrating birds relying on the field become hopelessly confused? And when will it happen? Some estimates say “soon,” which, for a geophysicist, could be in the next 10,000 years.

The Earth's magnetic field surrounds our planet like an invisible force field—protecting life from harmful solar radiation by deflecting charged particles away. Far from being constant, this ...

Unlike the Earth, Mars does not have a strong, global magnetic field. This field helps to protect our planet from cosmic rays and retain its atmosphere.
