There's a Link Between the Earth's Atmosphere and its Magnetic Field
By Matthew Williams (https://ift.tt/3RrSXOy)

The solar wind flows around Earth's magnetic field. A new NASA study suggests that the amount of oxygen in the atmosphere and strength of the magnetic field have been correlated for more than half a billion years. NASA's Goddard Space Flight Center/Conceptual Image Laboratory

The Earth's magnetosphere is a giant magnetic field that arises from the flow of material deep inside the planet. Because the flow of material isn't constant, the strength and shape of the magnetosphere can change over geologic time. But researchers have found that changes in the magnetosphere seem to be correlated with fluctuations in the amount of oxygen in the Earth's atmosphere. Both could be responding to a single underlying process.
