Some contend that there's an object coming from the other side of the Sun that's will cause a pole shift.
By Nathan Case, Lancaster University
Like most planets in our solar system, the Earth has its own magnetic field. Thanks to its largely molten iron core, our planet is in fact a bit like a bar magnet. It has a north and south magnetic pole, separate from the geographic poles, with a field connecting the two. This field protects our planet from radiation and is responsible for creating the northern and southern lights - spectacular events that are only visible near the magnetic poles.
However, with reports that the magnetic north pole has started moving swiftly at 50km (31 miles) per year - and may soon be over Siberia - it has long been unclear whether the northern lights will move too. Now a new study, published in Geophysical Research Letters, has come up with an answer.
Our planetary magnetic field has many advantages. For over 2,000 years, travellers have been able to use it to navigate across the globe. Some animals even seem to be able to find their way thanks to the magnetic field. But, more importantly than that, our geomagnetic field helps protect all life on Earth....
