Experiments suggest an unusual magnetic material could help harness energy from Earth’s rotation. But not everyone is ...

In an experiment, a team of physicists investigated whether we could harness the Earth's rotational energy to generate ...

Samples from Nasa's Apollo missions hinted that it existed more than three billion years ago, with strengths rivalling Earth's present magnetic field, which ranges from 25 to 65 microteslas.

A weak magnetic field likely attracted matter inward, contributing to the formation of the outer planetary bodies, from ...

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 poles are constantly on the move, but they haven’t drifted far enough to actually flip in the modern age. Researchers know that Earth’s poles have flipped in the past ...

A massive 'gravity hole' pulling down the Indian Ocean has stumped scientists for years, but the mystery may have just been ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...

High-speed winds from a spot on the sun’s surface may affect Earth’s magnetic field, pulling the phenomenon further south.

But it’s more important than you might think. The Earth acts like a giant bar magnet, with a magnetic north and south pole. Confusingly, these are not in the same place as the geographic north ...
