The magnetic north pole is a bit south east of the true north pole. Depending on where you live the variation or declination can vary. In the Pacific Northwest it is off by 19.5 degrees east. If you happen to live near the line of longtitude that passes from the true north down thru magnetic north you would not notice any difference. If you have ever seen a nautical chart it shows a compass rose with both magnetic & true north readings. In order to navigate from compass readings to chart course you must always add or subtract the variation depending on what part of the earth you are sailing on. All compasses point to the magnetic north which is not necessarily true north.
