Uranus' magnetic field flips daily like a switch: Study
Uranus' magnetosphere flips on and off like a switch daily as it rotates along with the planet, according to a Georgia Tech study. Unlike Earth, Uranus rotates sideways, tilting the magnetic field by 60Âº from its axis. The tilt causes the magnetosphere to "open" and "close" to solar winds during its 17-hour full rotation.
