The big iron ball in the center of the Earthis is suspended in liquid rock and not perfectly centered, spinning but not orientated perfectly to the Earths poles. STherefore, the Earth tends to wobble around it and the magnitic poles are far from the geographic poles. As seen from any place, these poles are then relatively in different directions.
What else can I help you with?
What is the approximate number of degrees east or west of true north that a magnetic compass would point in your lab?
It depends on where you live: the compass points towards the magnetic north pole, which is in northern Canada about 10-15° from the true North Pole, but is moving slowly north. There is a calculator on the Canadian Geological Survey website at http://geomag.nrcan.gc.ca/apps/mdcal-eng.php.
Where was magnetic north verses geographical north 5000 years ago?
Approximately 5000 years ago, magnetic north and geographic north were not aligned as they are today. The difference between the two, known as magnetic declination, would have varied depending on the specific location, but it could have been several degrees. This variation is due to changes in the Earth's magnetic field over time.
When does the north pole become the south pole and the south pole become the north pole?
Answer The answer is no, of course not! It is the magnetic polarity of the earth that is being flipped, not the locations of Magnetic North and Magnetic South. Remember, 'Magnetic North' and 'Magnetic South' are locations, not magnetic poles. So even if their magnetic polarities flip, the names of the locations won't ever change! All that would happen is that the magnetic field would reverse, and your compass would point to Magnetic South instead of Magnetic North.Think of it this way, if the magnetic polarity of the earth flips, you wouldn't swap the names 'Arctic' and 'Antarctic'! So, why would you swap the names 'Magnetic North' and 'Magnetic South'!!!!!
Why is position of crescent moon different in Florida than in the Midwest?
The orientation of the crescent Moon depends on the time, the position of the observer (that's you), the declination of the Sun (how far north or south of the equator) and the declination of the Moon. If the crescent Moon were a bow, the arrow would be pointed toward the Sun.
Why do orienteering maps have magnetic North Pole instead of the true North Pole?
That is because the map is used with a magnetic compass. Since the needle on the compass points in the direction of magnetic north it is easier to use the map with the compass if the lines drawn on the map indicate magnetic north.
Calculate the magnetic bearing from a true bearing of 180 degree from a map with declination of 8 degrees east?
To calculate the magnetic bearing, you would subtract the declination from the true bearing if the declination is east, or add the declination if the declination is west. In this case, since the declination is 8 degrees east, you would subtract the declination from the true bearing of 180 degrees. Magnetic bearing = True bearing - Declination Magnetic bearing = 180 degrees - 8 degrees Magnetic bearing = 172 degrees
What would your magnetic declination be if you were using a compass in Vail Colo.?
9 degrees 32 minutes EAST (positive)
To convert a grid azimuth to a magnetic azimuth you will need to know g-m angle. where would you look for this piece of information?

Why would magnetic declaration be different for different locations on the earth?
First of all, we're pretty sure that you're referring to "variation", not "declaration".Magnetic variation is the difference between the direction from you to the north pole (called "true north"), and the direction in which your magnetic compass points.That difference changes with your position on earth, because the north pole and theplace your compass points to are two different places. If you were standing at the point that's exactly halfway between them, then your compass would point exactly away from the north pole. And if you're not between them, but you're standing on the extension of the line between them, then your compass it pointing at the north pole, because both points are in the same direction from you.If you look at a navigational map, you will see lines of magnetic variation printed on the map. If you read your magnetic compass and apply the magnetic variation (printed on the map), you can calculate the direction of TRUE north.

How many locations of hurricane grill and wings are there in Michigan?
17 different locations, I would know since I have been there numerous times
Would your mass be different in different locations?
Yes,It would be different because the force of gravity.If you go higher like on mountains your weight would be less but you'll look the same.
