"The current behaviour of magnetic north is something that we have never observed before," says global geomagnetic field modeller William Brown, from BGS. "Magnetic north has been moving slowly ...

When an electric current passes ... the spinning Earth, the magnetic fields generated within the liquid core would cancel one another out and result in no distinct north or south magnetic poles.

1 illustrates the nightly coincidence of micropulsations, measured with a 6-ft. diameter magnetic north axis loop antenna of 21,586 turns and 3914-Å. auroral pulsations from 70° of sky measured ...
