Story summary

University of New Hampshire researchers Emily McDougall and Matthew Argall detected magnetic switchbacks in Earth's magnetic field.
They found plasma in Earth's magnetic field originated from the Sun, driving interactions between open and closed field lines.
These interactions release energy and form switchbacks.
The findings were published in the Journal of Geophysical Research: Space Physics, and could improve understanding of geomagnetic storms and related solar events.
