Cutting a bar magnet in half won't get rid of its poles. It'll just produce two magnets, each with a north pole that will be attracted to the other magnet's south pole, and vice versa. It's this ...

The south magnetic pole is also moving, though at a much slower rate (10-15km a year). This rapid wandering of the north magnetic pole has caused some problems for scientists and navigators alike.

Over the past 150 years, the magnetic North Pole has casually wandered 685 miles across northern Canada. But right now it's racing 25 miles a year to the northwest.

Imagine a bar magnet inside Earth, more or less aligned with the axis, where the ends of that magnet lie close to the geographic North and South poles of the planet. The magnetic field lines ...

In general Earth’s magnetic field is getting weaker, leading scientists to say that it will eventually flip, where north and south pole changes polarity, like a bar magnet flipping over.

The updated version of the World Magnetic Model was released on Dec. 17, with a new prediction of how the magnetic north pole ...

Since the magnetic north pole was first measured in 1831 it has moved about 1,400 miles toward Siberia. ... where north and south pole changes polarity, like a bar magnet flipping over.

WASHINGTON — True north isn't quite where it used to be. Earth's north magnetic pole has been drifting so fast in the last few decades that scientists that past estimates are no longer accurate ...

Earth's north magnetic pole has been drifting so fast in the last few decades that scientists say that past estimates are no longer accurate enough for precise navigation. On Monday, they released an ...
