Likewise, a wire passing through a magnetic field creates an electric current within the wire. This is the basic principle that allows electric motors and generators to operate. In the Earth (see ...

Earth's magnetic north pole is on the move, prompting updates to the World Magnetic Model (WMM). This crucial tool for ...

The Earth’s magnetic north pole has been slowly inching its way across the Arctic for decades, but recently, its path […] The ...

Creatures from migratory eels and other fish species to insects to birds tap into the Earth’s magnetic field to navigate, sometimes many thousands of miles. But so far, evidence has been scant for any ...

David Bressan is a geologist who covers curiosities about Earth. Without its magnetic field, life on Earth would not be possible since this shields us from harmful cosmic radiation and charged ...

Earth’s magnetic field, generated by movements within its molten iron core, serves as a protective shield against solar winds ...

In mid-December of 2024, scientists officially updated the World Magnetic Model (WMM), which helps keep track of our planet’s magnetic north and its chaotic and relatively unpredictable movements.

This, they say, has caused a titanic shift in the planet’s magnetic field. Essentially, the molten iron at the core of our planet helps to determine where Earth’s magnetic field downs down.

Earth's magnetic field results from a swirling sea of electrically charged molten iron in the planet's outer core. Heat currents and Earth's spin both fuel the movement of this liquid iron.

The reversal could actually have a beneficial effect on Earth. The sun is on the verge of a significant event: a magnetic field reversal. The sun undergoes such a reversal every 11 years ...
