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.

How do you calculate magnetic declination?
The difference between True North and the direction that a magnetic compass points for a given location. Example: the magnetic declination for Seattle, Washington per the NOAA is 16° 55' east (as of 04/2010). This means that magnetic north is predicted at 16° 55'east of True North at that time.
What location on Earth do compass needles point to?
The Earth has its own magnetic field because there are electric currents and magnetic materials in its core. Roughly speaking, the shape of the magnetic field lines are such that they go between the "top" and into the "bottom" of the Earth. Top means Arctic and bottom means Antarctic. A compass, or any other simple magnet, will align itself with the magnetic field lines in its vicinity. Roughly speaking, when two magnets are near each other, the "north" end of one magnet points in the direction of the "south" end of the other. The north end of a compass points towards the geographic north pole. That is in the Arctic. It is sometimes call the north magnetic pole because it is near the top of the northern hemisphere of the Earth. That is the answer to this question. Note however that the "north pole" is a geographic location. As a magnetic pole of the magnet that is Earth, it is a "south" magnetic pole. One can understand how it arose historically that is was given exactly the opposite of the correct assignment as a magnetic pole. Finally, it should be said the the magnetic field of the Earth has a number peculiar features and its details are much more complicated than a description of an ideal magnet, hence in detail, a compass direction has a lot of complex variations depending on where one is located on Earth.
What is the magnetic quantum number of copper?
"Magnetic quantum number" is a quantum number that corresponds to individual electrons, not to an entire atom.
How the magnetic field of an electromagnet defends on the current and the number of coils?
The magnetic field of an electromagnet is directly proportional to both the current passing through its coils and the number of coils. Increasing either the current or the number of coils will result in a stronger magnetic field, while decreasing them will weaken the magnetic field. This relationship is described by Ampere's law and the concept of magnetic flux.

Are the magnetic north and the geographic North Pole always the same distance apart?
Actually no. Magnetic north shifts over time. It has to do with the rotation of the liquid iron inside the earth. I can't remember the exact number but I think you can estimate true north by adding 5 degrees to your compass.
Why are airport runway numbers always in increments of 18?
The runway numbers are in magnetic direction. Runway 27 is 270 degrees magnetic (rounded off to the nearest 10 degrees). Runway 04 is 040 degrees magnetic. When you are making your approach, your runway of intended use (into the wind) will be your magnetic direction on your compass. When you see an L, C, or R after the number there would be two or more runways in the same direction on that airport. The letters stand for Left, Center, or Right depending on which runway you would be assigned to land on. As runways can be approached from either direction the difference between the two number will reflect the 180° difference, thus increments of 18.
How do you take a bearing?
You take a bearing by pointing your compass at the target (or direction you want to go) and reading the number on the compass. There are 360 degrees in a circle, with East being at 90 degrees, South-East being 135 degrees, South being 180, West 270, North 360 (or zero) and etc. etc.

How many degrees away from magnetic south is true south in Utah county Utah?
As of Jan 2008 the magnetic declination for the SLC, UT area was 12.5 degrees to the west. It has decreased about 1.5 degrees in the last 10 years and 2.5 degrees the 25 years before that. That means that right now 'True South' for SLC is 12.5 degrees west of magnetic south, but expect that number to decrease in the future. This information is useful in new construction when orienting the location of a home designed to work on passive solar designs for lower heating and cooling expenses.
How do you find true north?
I presume your question is how to convert a compass reading to a map reading. If so read on... 1. Determine if magnetic north points to the east or west of true north in your location. (See magnetic declination) 2. If you think of easterly declinations as always having positive values and westerly declinations as having negative values - imagine a directed number line where values to the right (East) of 0 (which we will call True North) are positive and numbers to the left (West) are negative. Now all one need remember is this mnemonic - MTA (Magnetic to True ADD). Example 1: Magnetic Heading is 23 degrees in an area where East Decl. is 7 degrees. True North = 23 + 7 = 30 degrees Example 2: Magnetic Heading is 150 degrees in an area where West Decl. is 14 degrees. True North = 150 + (-14) = 136 degrees
