Magnetic Fields and the variation

Magnetic Fields and the variation

Here is a helpful map if you find yourself walking with a compass and needing to find true north. The lines represent the degree difference between true north and magnetic north.

Here in the PNW the difference is about 15 degrees, while in the middle of the US the difference goes to 0.

Perhaps the most amazing observation is the latitude of the southern pole, which is close to 65 degrees. An eventual geomagnetic reversal will be something to see, albeit it might take a thousand years to complete.

As long as the poles stay out of the right half plane we will be ok! Happy New Year!
