What Are Magnetic Field Reversals. However, the time between reversals is highly. Earth's magnetic field is unstable. Fluctuations in the magnetic field caused by the movement of metallic material in the outer core have brought about full reversals of the magnetic field's polarity in earth's past. Many times over our planet’s history, earth ’s magnetic poles have reversed, meaning that sometimes a compass pointing north will be. Extensive analysis now shows that the earth's magnetic field has reversed about 170 times over the last 100 million years. But our new research shows that there is a relationship between the earth’s magnetic field and the amount of ancient ocean floor that descends from the surface into the hot ductile mantle beneath,. Much of this behaviour remains a mystery, but a. Interestingly, the magnetic field may. Our planet's magnetic field reverses about once every 200,000 years on average. Not only does it vary in intensity, but from time to time it flips, with the poles reversing sign. By magnetic reversal, or 'flip', we mean the process by which the north pole is transformed into a south pole and the south pole becomes a north pole. Scientists continue to evaluate data, and there is much disagreement over how long these periods of magnetic polarity last and whether the reversals happen at predictable intervals or are irregular and unexpected.
