Whats the difference between normal magnetic polarity and reversed magnetic polarity?

Answer 1

The terms refer to the direction of earth's magnetic field. The earth has a field very much like a standard bar magnet, with a north and a south magnetic pole. Unlike a bar magnet, whose field is locked into the solid crystals of the magnet, the earth's field is generated by moving molten iron in the outer core. This motion is very complex and at times, the complexity results in the north and south end of the earth's field trading places. It's as if you turned the bar magnet upside down, but did it without actually moving the bulk of the earth (your compass's north needle would point to Antarctica instead of Siberia). This happens at time intervals of a few hundred thousand years to tens of millions of years and is not at all periodic or cyclical.

Because the current situation is what humans have always known, we call it NORMAL polarity (North magnetic pole near north geographic pole). The opposite situation is known as REVERSED polarity (north magnetic pole near south geographic pole). Except for the direction of the poles, there is no
difference between normal and reversed polarity magnetic fields and no significant effects on life or on geologic processes

Answer 3

Normal Polarity

Answer 4

We call the current arrangement "normal" but for more than 50% of the Earth's life, the north magnetic pole has been in the south. It will go back there again soon. (Soon in geologic time, not human)

Answer 5

there is no difference
