This question is not as simple as it seems, and a few minutes of googling did not drop the answer in my lap.

A comment at I never adjust for true north. Is this bad practice? suggesting that:

True north and magnetic north are basically the same thing

started me on a search for a quality answer I could use in a response. I believe the distance between them is larger than size of many small countries, so not sure I would call them basically the same thing.

How much distance (miles/kilometers) is there between True North(Geographic) and Magnetic North Poles?
