Book excerpt: Excerpt from Journal of the Washington Academy of Sciences, 1913, Vol. 3 Sutherland's hypothesis avoids the difficulties pointed out by Rowland5 in 1879 as also some of those advanced in connection with other theories. Unfortunately, however, it thus far admits of no conclusive proof, chiefly for the reason that it leads to an expression for the magnetic potential precisely the same, as far as effects on or above the Earth's surface are concerned, whether the magnetic field be due to an elemental magnet at the center of the Earth, or to a uniformly magnetized sphere, or to an appro priate system of electric currents imbedded in the Earth, or to a rotating electrically charged sphere such as Sutherland supposed, or to a combination of these causes. Mathematically the mag netic fields ascribed to these various, distinct causes can not be differentiated from one another.
