WebMagnetic Reversal definition: A change in the polarity of a magnetic field in which magnetic north and south are reversed. WebA magnetic reversal occurs when the north and south poles of the Earth's magnetic field flip or switch positions (Figure 6). This is called a geomagnetic reversal . The history of geomagnetic reversals is preserved in older and younger rocks (see Figure 5). WebMagnetic reversals- Evidence suggests that the earth's magnetic field has periodically reversed its polarity in the past. During the present time lines of magnetic force leave the earth's magnetic south pole and go to the magnetic north pole. During a magnetic reversal the lines of force leave the north pole and go to the south pole. muhammad ali contribution to black history
