Scientists believe that the weak magnetic field let a lot of ... a two-billion-year-old rock suggested that the magnetic ...

Scientists have discovered that the 'weak spot' in Earth's magnetic field is growing, allowing harmful radiation to come closer to our planet's surface. The region, known as the South Atlantic ...

Observations suggest that weak magnetic fields in these voids could be remnants ... hypothetical particles that may help explain dark matter and the strong force in particle physics.

The field often gets very weak, then bounces back, never having flipped. As Ron Merrill, a magnetic-field specialist at the University of Washington remarked when asked whether we're in for a ...

Combined with previous sample-return data and observations by spacecraft in lunar orbit, the new results make a strong case ... the Moon had a weak global magnetic field about 1/20th the strength ...

When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by ...
