In the early 1960s Earth scientists found through dating and paleomagnetic studies of terrestrial lavas that Earth's magnetic field, which is created by the circulation of core materials, had reversed polarity frequently and regularly in the past at intervals of about half a million years, with each reversal probably taking only a few thousand years.
