Mars Does Have a Magnetic Field of Sorts – And We've Finally Got Data to Map It - ScienceAlert

It gives scientists a much greater understanding of how Mars might have lost much of its atmosphere over the course of billions of years, as well as how interactions between the solar winds and Mars' magnetosphere are playing out today.

These currents interact with the incoming solar wind, causing it to envelop Mars and flow around it like spaghetti noodles around a basketball.

What's also interesting for the researchers is the detail of the interplay between the solar winds and the electric currents, and how energy is transferred between the upper atmosphere, the magnetosphere, and the solar wind.

"The currents flow in the upper atmosphere, with the strongest current layers persisting at 120-200 kilometres (75-124 miles) above the planet's surface.".
