Earth's magnetic field weakens every 200 million years, new study says
... is today, it wasn’t the flip rate that was necessary the problem, but a weakening of the magnetic field strength instead. When Earth’s magnetic field is weakened, the drop in strength allows more energetic particles into the upper atmosphere, which...

Revealing the magnetic universe
...whereas in the dense central regions, the matter flows perpendicular to the direction of the magnetic field. Magnetic fields are playing an important role in shaping these filaments. But for stars to form, these filaments will need to ...

Cassini finds surprises for Saturn's magnetic field
... of the spectacular ringed planet has no discernible tilt, a finding that is at odds with scientists' theoretical understanding of how magnetic fields are generated. The discovery also means that the true length of Saturn's day is still unknown. The...
