Earth's Magnetic Field Booms Like a Drum, But No One Can Hear It

You may not be able to hear it, but Earth's magnetic shield booms like a drum when it's bombarded by strong impulses, including those from solar wind, a new study finds.

By Laura Geggel, July 06, 2022

"Every time an impulse strikes the shield's outer boundary — a region known as the magnetopause — jolts ripple through its surface and then are reflected back once they reach the magnetic poles, just like the face of a drum ripples as a percussionist beats it.

"Movements in the magnetopause can impact the flow of energy within Earth's space environment, Archer noted. For instance, the magnetopause can be impacted by solar wind, as well as charged particles in the form of plasma that blow off the sun. These interactions with the magnetopause, in turn, have the potential to damage technology, including power grids and GPS devices."
