Weary of being captive to geopolitics, car companies are looking for ways to replace powerful rare-earth magnets in electric motors. By Jack Ewing A geomagnetic storm made the aurora borealis visible ...

In 1845, physicist Michael Faraday provided the first direct evidence that electromagnetism and light are related. Now, it turns out that this connection is even stronger than Faraday imagined. In his ...

The study of the earth's changing magnetic field at geological and societal timescales, especially through the analysis of remanent magnetism in rocks and human artifacts. The main function of the ...

Palaeomagnetism is the study of past variations in the Earth’s magnetic field as reconstructed from the rock and archaeological records. In addition to providing information about the intensity, ...

Magnetic materials are materials studied and used mainly for their magnetic properties. The magnetic response of a materials is largely determined by the magnetic dipole moment associated with the ...
