Magnetic Reversal Definition Geology. The earth has a magnetic field, as can be seen by using a magnetic compass. every half million years, on the average, the earth's magnetic polarity reverses, and so does the magnetization of the ocean floor. liquid lava, which hardens into rock, contains grains of iron oxides that react to the earth's magnetic field by pointing toward the magnetic pole as the rock solidifies. records indicate that over the last 160 million years, the magnetic pole has reversed its polarity at least several hundred times. When lavas or sediments solidify, they often preserve a signature of the ambient. geomagnetic reversal, an alternation of the earth’s magnetic polarity in geologic time. magnetic field reversal refers to the phenomenon where the earth's magnetic north and south poles switch places over. what do we mean by a magnetic reversal or a magnetic 'flip' of the earth? We can see evidence of magnetic polarity reversals by examining the geologic record.
