The Reporter (OP) User ID: 1194139 Netherlands 01/09/2011 05:57 PM Report Abusive Post Report Copyright Violation | But it's not normal to go from left to right around the north and it goes between 5 degrees left off north and 7 to the right in about seconds. I noticed this in iphone but maybe it's a bug so walked upstairs to get the old good army thing and it does the same inside and outside the house. you are being tested.... remain calm... |

There is something called "declination"- which is the difference between the two. I think it is normally something like a 17 degree difference. Plus, lots of compasses are cheap garbage which are inaccurate by a few degress already. Combine those two things and this is why plenty of hikers get lost every year and conspiracy nuts cry foul.

Magnetic North Pole Shifts, Forces Runway Closures at Florida Airport [link to www.foxnews.com] Thanks to the fluctuations in the force, the airport has closed its primary runway until Jan. 13 to change taxiway signs to account for the shift, the Federal Aviation Administration said. The poles are generated by movements within the Earth's inner and outer cores, though the exact process isn't exactly understood. They're also constantly in flux, moving a few degrees every year, but the changes are almost never of such a magnitude that runways require adjusting, said Paul Takemoto, a spokesman for the FAA. The magnetic fields vary from place to place. Adjustments are needed now at airports in Tampa, but they aren't immediately required at all airports across the country. So just how often is something like this necessary? "It happens so infrequently that they wouldn't venture a guess," Takemoto told FoxNews.com. "In fact, you're the first journalist to ever ask me about it." |
Anonymous Coward User ID: 1168836 United States 01/09/2011 06:07 PM Report Abusive Post Report Copyright Violation | The magnetic declination does not remain constant in time. Complex fluid currents of the elements iron, nickel, and cobalt flow in the outer core of the earth (the molten metallic region lies from 2800 to 5000 km below the earth's surface) generating a magnetic field. The poles of this field do not coincide with the unchanging true north and south — the axis of rotation of the earth. The change in the magnetic fields is known as secular variation. Local anomalies originating in the upper mantle, crust, or surface, cause further distortions. Ferromagnetic ore deposits; geological features, particularly of volcanic origin, such as faults and lava beds; topographical features such as ridges, trenches, seamounts, and mountains; ground that has been hit by lightning; cultural features such as power lines, pipes, rails and building; personal (ferrous) man-made items such as a stove, steel watch, or even your belt buckle, frequently induce an error of three to four degrees. If you think there are iron deposits in your area, you will want to check with a local surveyor to make sure you are pretty close on the magnetic declination. |
