to na samom dele ego strelka ukazyvaet ne na real'nyi Severnyi polyus Zemli. 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. Na segodnyashnei kartinke strelkoi pokazano nastoyashee
