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.

How do you convert true bearings to magnetic?
To convert true bearings to magnetic bearings, you need to account for the magnetic declination (also known as magnetic variation) at your location. If the magnetic declination is east, you subtract it from the true bearing; if it is west, you add it. For example, if your true bearing is 100° and the magnetic declination is 5° east, the magnetic bearing would be 95°. Always check local charts or resources for the most accurate declination values.
How would you determine declination at your home?
To determine the magnetic declination at your home, you can use a compass alongside a declination calculator or map. First, find your geographic coordinates (latitude and longitude) using a GPS device or online mapping service. Then, input these coordinates into a declination calculator, or refer to a magnetic declination map, which indicates the angle between magnetic north and true north for your specific location. Alternatively, you can also use a reliable app that provides real-time declination based on your location.
If the magnetic North arrow in the declination diagram is to the left or north Gridline then what should the Compass reading be?
If the magnetic North arrow in the declination diagram is to the left of the north gridline, this indicates that magnetic North is west of true North. To obtain a compass reading that aligns with true North, you would need to add the declination angle to your compass reading. Therefore, if the magnetic North is to the left, the compass reading should be adjusted accordingly to the right (east) to compensate for the declination.
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.
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 is the magnetic declination of Austin tx?
As of 2023, the magnetic declination in Austin, Texas, is approximately 6.5 degrees east. This means that when using a magnetic compass, one would need to adjust their heading about 6.5 degrees to the west to find true north. Magnetic declination can change over time due to shifts in the Earth's magnetic field, so it's important to check for updates if precise navigation is required.
What would your magnetic declination be if you were using a compass in Vail Colo.?
9 degrees 32 minutes EAST (positive)

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.
What is the approximate number of degrees east or west of true north that a magnetic compass would point in your lab?

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.
