In miles,what is the difference between true North, and magnetic North ?

Question

I noticed, while in Monterey, Mex., while using GPS, my magnetic compass was way off, compared to OK. City !

Answer 1

590 miles

I quote "True north is a constant and refers to the geographic North Pole. Magnetic north tends to shift and refers to the pole of the Earth's magnetic field. In mid 2002, true north and magnetic north were approximately 590 miles apart. "

Answer 2

as was said, it's angular, not miles......if you were on anorth south line running between say, Chicago and Mississippi then mag north and true north are the same......if you were in Seattle or Halifax you'd see about a15 degree difference.......type in "magnetic variation" to the search bar and be amazed at what you get.....

this is also why you have to be REAL Careful when you specify a direction.....are you talking true or magnetic because there can be ( as above 15 degrees or more ) difference which very quickly is the difference between being home or lost......or afloat or aground....
also type into search "True Virgins Make Dull Company" or "Can Dead Men Vote Twice" and see what you get.....

Answer 3

The difference is angular, not linear.
