Arctic Aspects of Geomagnetism

Relation of magnetic field to position on a uniformly magnetized sphere.
Lines of equal magnetic total intensity for 1925, according to Fisk.
Lines of equal magnetic horizontal intensity for 1925, according to Fisk.
Magnetic meridian curves for 1925, according to Fisk.
Distribution of magnetic activity, 1932-33. The numbers on the lines denote average range of total-intensity disturbance in gammas for 60 selected days of considerable disturbance. (After Vestine.)
Chart of magnetic meridians for a portion of northern Canada constructed from recent Canadian declination observations by the Dominion Observatory, Ottawa. The magnetic meridians converge on Prince of Wales Island where the region of the north magnetic pole as at present determined is shown by a circle.
Auroras Are Most Frequent in Northern Canada and Siberia, Not Near the North Pole.
