Reply to comment by wazoheat in Around 550 million years ago the earth's magnetic field almost collapsed, but then strengthened a few million years later. Scientists say this may have been due to the formation of the inner core. But why exactly would that cause the magnetic field to get stronger? by somethingX
What impact would a near collapse of the magnetic field have on the planet? Does 550M years ago coincide with any known extinction periods?
