The North and South magnetic poles have switched places before - and they’ll do it again. This video investigates what this means for humanity, including the risks of power grid failures and increased ...

The Earth’s magnetic field is a shield that protects us from the sun’s harmful radiation. It’s a fascinating phenomenon that ...

But it’s more important than you might think. The Earth acts like a giant bar magnet, with a magnetic north and south pole. Confusingly, these are not in the same place as the geographic north ...

A magnet has opposite ends called a north pole and a south pole. Between the poles is a magnetic force that we can’t see. This is a non-contact force. The area around the magnet that is affected ...

Earth's magnetic field is what protects our planet from harmful space radiation. However, our protective shield might soon go into a transformation that could threaten the lives on Earth.

The instructors who imparted this wisdom had never flown into the ultimate Cone of Confusion, the ones over the magnetic north and south poles. There, the magnetic lines of force are vertical ...

The Earth’s magnetic field is predominantly a geo-axial dipole, with north and south magnetic poles located near the geographic poles that undergo periodic reversals and excursions.

Every so often, our planet's magnetic poles reverse polarity (see When Compasses Point South). Compass needles have always pointed north; in a reversal, they would point south. You could perhaps ...

You can easily know about its presence with the help of a magnetic compass, which always points north. Earth is similar to a magnet bar and the north and south poles represent the two sides.
