Pictures may enliven us, but other data, such as information about magnetic fields, add a huge amount to our understanding of ...

The magnetic north pole, meanwhile, is the point in the Northern Hemisphere where Earth's magnetic field lines point directly into the planet. The complex motion of the outer core causes the ...

The lines of Earth’s magnetic field point from one pole to the other. When the solar wind approaches Earth, it pulls at the magnetic field, distorting its field lines. Eric Donovan, an assistant ...

Most of the time, the Earth and Sun’s magnetic fields are misaligned, leaving our planet’s field less open to the aurora-causing effects of the solar wind. However, towards the equinox, the two fields ...

One of the many unseen forces to which you owe your existence is magnetism. If it weren’t for the magnetic field that surrounds our planet, blocking cosmic radiation and solar wind, Earth would likely ...

The direction of the magnetic field switches to the opposite direction ... keeps the electron spins from staying aligned, so they point in random directions. In the unmagnetized state, the ...
