Pipistrelle bats have a magnetic compass and calibrate it at sunset, according to a new study. An international team of researchers has used behavioral experiments to show that two different ...

Scientists have finally confirmed that Earth is wrapped in a subtle but global electric field, a planetary-scale energy ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

The magnetized needle of a conventional compass wants to align with Earth’s magnetic field—helpful, unless you’re near the poles, where the field tugs straight downward, rendering magnetic compasses ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a given location.

Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The ...

The Earth’s magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it ...
