WebEarth’s magnetic field can be viewed roughly as induced by a huge bar magnet at Earth’s center pointing along Earth’s magnetic axis which changes very slowly. At present, the geomagnetic south pole is near the geographic north pole and the geomagnetic north pole is near the geographic south pole. Like the magnetic field produced by a WebEarth’s magnetic field is in a permanent state of flux. Magnetic north wanders, and every few hundred thousand years the polarity flips so that a compass would point south instead of north. Moreover, the strength of the magnetic field constantly changes – and it is currently showing signs of significant weakening. high beam sensor
