As you all know the earth is a giant magnet. As a giant magnet antarctica would be the north or south pole of that magnet?

@freemo it's north because a regular magnet's south end is attracted to the north end of an external magnetic field. Opposite poles attract. However this varies in time; a geomagnetic reversal could occur at any time and flip the polarity of the Earth's field.

@hector well if a magnetic reversal did occur I wonder if we would rename the poles of either magnets or the earth :)

@xorman perhaps, but there is still only one correct answer. And while the specific definition is somewhat arbitrary it is absolute in the way it is defined.

@freemo depending on the epoch, can be north or south, the magnetic poles are constantly moving. Right now they are slightly different from the geographic poles i.e., the magnetic south pole is nearby Antarctica.

@rvlobato We are talking exclusively within the scope of human history, in which case each pole has been consistently on one side of the planet or the other, with some degree of drift but one of the poles has always been within the borders of antarctica within the last several hundred years at least.

@freemo I'm guessing south since polarity was probably defined from maps and historical scientists would have probably made it intuitive to understand.

@Demosthenes well you would be correct that maps ultimately led to how we defined magnetic poles... answer me this ifi stick a magnet in some water and make it float and basically create a compass the north pole of the magnet points where? And yea feel free to use the logic that anctient scientists would have defined the poles of a magnet based off the idea of north on a map already.

@freemo my guess would be that the north pole of the magnet would point south.

@Demosthenes other way around, but your instinct is right at least that the poles of the earth and the poles of a magnet disagree.. its just its the earth that is backwards not the magnet.
