A magnetic field is invisible, but it can be detected using a magnetic compass. A compass contains a small bar magnet on a pivot so that it can rotate. The compass needle points in the direction ...

A team of physicists at the University of Cambridge has unveiled a breakthrough in quantum sensing by demonstrating the use ...

Eurasian reed warblers (Acrocephalus scirpaceus) appear to calculate their geographical position by drawing data from different distances and angles between magnetic fields and the Earth’s shape.

When the colder core begins to draw heat from the outer layer, and lighter elements such as sulphur are released, they report, it initiates convection — which in turn creates a magnetic field.

The Earth's magnetic field is essential to life as we know it. But it’s something we can never see – or hear, until now. In a recent study released on Oct. 10 by the European Space Agency ...

The sun has a powerful magnetic field that creates sunspots on the star’s surface and unleashes solar storms such as the one that bathed much of the planet in beautiful auroras this month.
