Magnetic Poles to Flip

[Brian Mcculloch Glasgow 0 9]

The Earth has a fierce molten core that generates a magnetic field capable of defending our planet against devastating solar winds.

 

The protective field extends thousands of miles into space and its magnetism affects everything from auroras to power grids.

 

But this field, so important to life on Earth, has weakened by around 15 per cent over the last 200 years.

 

And this, scientists claim, could be a sign that the Earth’s poles are about to flip.
