Geomagnetic dating ultramotora online dating
Unlike the Earth's geographic equator, the magnetic equator is not fixed, but slowly changes.
At the magnetic poles, a dip needle stands vertical (dip=90 degrees), the horizontal intensity is zero, and a compass does not show direction (D is undefined).
Back to top To measure the Earth's magnetism in any place, we must measure the direction and intensity of the field.
The Earth's magnetic field is described by seven parameters.
From these elements, all other parameters of the magnetic field can be calculated.
Back to top The geomagnetic field measured at any point on the Earth's surface is a combination of several magnetic fields generated by various sources.
