Any object with a magnetic field ... When the solar wind approaches Earth, it pulls at the magnetic field, distorting its field lines. Eric Donovan, an assistant professor of physics and astronomy ...

A vast and evolving anomaly in Earth’s magnetic field, situated above South America and the southern Atlantic Ocean, ...

The intriguing possibility arises because Earth’s magnetic field does not rotate with the Earth like a physical object. Instead, it is created at each instant and remains essentially fixed in space.

Magnetotactic bacteria synthesize magnetic iron nanominerals ... that allows the bacteria to passively align with Earth's geomagnetic field lines in both the Northern and Southern Hemispheres.
