Question:

Where does a compass point true north?

There are two places, and I know that the Bermuda triangle is one of them, but thats all google seems to show when I try to find the other one...

So where is the other place?

  1. Draw a line from the true north pole to the magnetic north pole.  Extend that line south.  Any point on that line south of the magnetic north pole will point to both magnetic north and (beyond it) true north.


  2. The compass does not point true north. It points to magnetic north. There are lines of magnetic deviation which change from time to time. Look at an aeronautical sectional chart used by pilots. You will find magnetic deviation lines indicated on the chart. If you are west of the zero line of deviation you add to the compass reading, if east of the line of deviation subtract deviation.

  3. Any point south of the north magentic pole along the line of longitude that passes through the north magnetic pole.

    Draw a line from the north pole through Winnipeg to points south and you will be close on.

  4. The compass works because the Earth itself is a huge magnet. Its magnetic poles are oval areas about 1,300 miles (2,100 kilometers) from the geographic North and South poles. Irregular lines of force connect the magnetic poles, and the compass needle simply aligns itself with these lines of force. In a few places, where lines of force happen to lie along meridians (that is, where magnetic north and true north coincide), the compass points to true north. Near the magnetic pole the magnetic compass is useless because there the lines of force are vertical straight down into the Earth. In other areas iron ore deposits affect the compass's accuracy. Generally, however, the magnetic compass points a little east or west of true north. The angle between true north and magnetic north is called variation or declination. A compass rose, or graduated circle, is used to measure this angle on charts.

  5. I think the other respondents are missing the point of your question.

    I don't think it's true for the Bermuda Triangle.  You can look at the website listed below for what the variation is at this time.  To me, it looks like the 0 degrees variation passes through Duluth, Minnesota and just misses Minneapolis, St. Louis and Pensacola.  East of that line, the compass points west of true north and west of that line, the compass points east of true north.

    I found a government site where you can calculate the magnetic deviation for anywhere in the USA.  Check out the NOAA website below.  The magnetic compass points to true north at W89.730, N30.422.  Interesting.

  6. North Pole

    The North Pole is the northernmost point on Earth, lying diametrically opposite the South Pole. It defines latitude 90° North, as well as the direction of True North. At the North Pole all directions point south.
