Na samom dele, strelka kompasa pokazyvaet na Severnyi magnitnyi polyus Zemli. V nastoyashee vremya Severnyi magnitnyi polyus nahoditsya v severnoi chasti Kanady. Kazhdyi den' polyus opisyvaet ellipsy i v srednem dvizhetsya bolee 40 metrov v napravlenii na zapad. Imeetsya dokazatel'stvo, chto so vremen obrazovaniya Zemli, t.e. bolee 4.5 milliardov let nazad, Severnyi magnitnyi polyus obbezhal vsyu poverhnost' nashei planety. Nalichie magnitnogo polya u Zemli obuslovleno tem, chto u nee imeetsya chastichno ionizovannoe vneshnee yadro, kotoroe vrashaetsya bystree, chem poverhnost' planety.
