"The magnetic field is actually a superposition of fields from many current sources," geophysicist Terry Sabaka from NASA's Goddard Space Flight Centre in Greenbelt, Maryland explained in 2020.

The cause of SAA sits deep within Earth's surface. 'The magnetic field is actually a superposition of fields from many current sources,' geophysicist Terry Sabaka from NASA's Goddard Space Flight ...

Earth’s magnetic field originates from the movement of molten iron in the planet’s outer core, a process generating electric currents that create the field. However, this magnetic shield is ...

According to the ESA, “Our magnetic field is largely generated by an ocean of superheated, swirling liquid iron that makes up the outer core around 1,864 miles beneath our feet.

Earth’s magnetic field has behaved even more dramatically in the past, with the magnetosphere weakening so much that its polarity reversed. This flips the magnetic north and south poles, ...

Earth’s magnetic field was once 30 times weaker than it is today. This change may have played a pivotal role in the blossoming of complex life, new research found.

The poles of the sun’s magnetic field are fading away. But don’t panic: it’s all part of our host star’s usual 11-year cycle of activity.. Over the past couple of years, solar activity ...

For decades, scientists have been trying to understand why some rocks on the moon are strongly magnetized even though the moon has no magnetic field today. Moon rocks brought to Earth during NASA ...
