This rate of change is known as the geomagnetic secular variation, and current models using a constant variation over five-year periods are on average...

magnetic poles slowly change with time, which is referred to as geomagnetic secular variation. The effect of this means a map with the latest declination...

In geophysics, a geomagnetic jerk or secular geomagnetic variation impulse is a relatively sudden change in the second derivative of the Earth's magnetic...

A geomagnetic reversal is a change in the Earth's dipole magnetic field such that the positions of magnetic north and magnetic south are interchanged...
