Earth Axes in Pictures
What a wonderful geometry is the relationship between and betwixt earth’s magnetic and rotational axes. Here’s a study of them, in orthographic projection. Views 1, 2 & 3 are the xyz reference frame for the spin axis; views 4, 5 & 6 are the xyz reference frame for the magnetic axis.
It just looks prettier as an inverted image:
Note that the spot plumb above the spot where the magnetic axis is tangent to the inner core is approximately 6.5 degrees North latitude; 171 degrees East longitude. That puts it in the Marshall Islands, in the strait between Majuro and Mili Atolls, at about where the Equatorial Pacific Current gets going. Could someone out there run the trigonometry on that, give us a little better accuracy?
