WebDefinition: The geomagnetic field is the magnetic force field that surrounds the Earth. It is attributed to the combined effects of the planetary rotation and the movement of molten iron in the Earth's' core. Compasses, instruments that align themselves with the magnetic poles of the Earth, have been used in navigation for centuries. WebThe rate of reversals in the Earth's magnetic field has varied widely over time. 72 million years ago (Ma), the field reversed 5 times in a million years. In a 4-million-year period centered on 54 Ma, there were 10 reversals; at around 42 Ma, 17 reversals took place in the span of 3 million years.
