Earths 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.

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.

The dayside magnetosphere, the side of the magnetic field directly between the Earth and the sun, is a vast place. It usually extends some 10 times the radius of the Earth toward the sun, or about 41,000 miles (66,000 kilometers), said study lead researcher Martin Archer, a space plasma physicist at Queen Mary University of London.
