How earth magnetic north moves faster than magnetic soutj pole?
Answers
he earth's geographic poles are generally right where you would expect them to be: at the two opposing points about which the Earth seems to rotate. Magnetic poles used in compass navigation are another matter altogether. And neither pole pair is completely stationary.
The North magnetic pole is at a point where a dipping compass--a compass that allows the needle to move freely in a vertical plane (as opposed to the horizontal needle movements seen in most compasses)--points straight down into the earth. The South magnetic pole is the point where a dipping compass points up. A dipping compass points horizontally on the Earth's magnetic equator, also called the Earth's dip equator.
The magnetic poles are quite distant from their geographic counterparts. The North magnetic pole is located to the south in Northern Canada; the geographic South pole is at the center of the Antarctic continent, but the magnetic pole is hundreds of miles away, near the coast. In regions near the magnetic poles, compasses are virtually useless.
Complicating this issue is that these pole positions are not static--for either magnetic or geographic poles. The location of the North geographic pole wanders in a small erratic circle-like path, called the "Chandler wobble." This motion is less than 6 meters per year on the surface; a worldwide network of very precise global positioning satellite (GPS) receivers is used to determine this wander.
