This, in turn, affects convection in the outer core—the dynamo-like process that generates the magnetic field that protects life on Earth ... reversal would see the geomagnetic field temporarily ...

The Sun periodically ejects huge bubbles of plasma from its surface that contain an intense magnetic field. These events are called coronal mass ejections, or CMEs. When two of these ejections collide ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field ... origin of life on Earth ...

If these CMEs hit the Earth, they can trigger geomagnetic storms in our magnetosphere. "The mass ejected from the Sun carries ...

which occur when plasma from the sun interacts with the Earth’s magnetic field, according to the NOAA. When this solar material reaches Earth, geomagnetic storms and the northern lights can occur.
