Kuigi me seda tavaliselt ei m\u00e4rka, on Maa magnetv\u00e4li v\u00e4ga oluline, kuna see kaitseb meid ohtlike p\u00e4ikesetormide ja kosmosekiirguse eest. Ilma selleta ei oleks meie planeedil elu. Selleks et m\u00f5\u00f5ta seda magnetj\u00f5udu t\u00e4psemalt kui kunagi varem, valmistub ESA saatma orbiidile spetsiaalse missiooni nimega Swarm.<\/p>\n<\/div>\n<p>Swarm-kontseptsioon h\u00f5lmab kolme satelliidi konstellatsiooni, mis asuvad kolmel erineval polaarorbiidil k\u00f5rgusel 400\u2013550 km.

N\u00e4iteks nihkuvad p\u00f5hja- ja l\u00f5unamagnetpooluste asukohad maapinnal pidevalt. Ka v\u00e4lja tugevus muutub. Aeg-ajalt toimub pooluste vahetumine, nii et praegune p\u00f5hjapoolus muutub l\u00f5unapooluseks. Sellisel juhul n\u00e4itaks magnetkompass p\u00f5hja asemel l\u00f5una suunas!
