SAVIEZ-VOUS QUE NOUS VIVONS AU SOMMET D\u2019UN AIMANT G\u00c9ANT ?? \ud83e\udd2f<\/strong><\/h2>\n\n

Oui, la terre est comme un gros aimant avec un p\u00f4le nord et un p\u00f4le sud m\u00eame si cela semble incroyable !!<\/p>\n\n

Notre plan\u00e8te est constitu\u00e9e de couches aux compositions et aux propri\u00e9t\u00e9s physiques diff\u00e9rentes. La cro\u00fbte terrestre a une aimantation permanente et le noyau de la Terre g\u00e9n\u00e8re son champ magn\u00e9tique, soutenant la partie principale du champ. On pourrait donc dire que la Terre est donc un \u00ab aimant \u00bb.De plus, le champ magn\u00e9tique terrestre est vraiment important car il repr\u00e9sente un bouclier contre les vents mortels du rayonnement solaire et des \u00e9toiles lointaines. Si nous ne l\u2019avions pas eu, notre ozone aurait \u00e9t\u00e9 \u00e9limin\u00e9.<\/p>\n\n

Le g\u00e9oaimant peut \u00e9galement affecter les animaux.<\/p>\n\n

Vous \u00eates-vous d\u00e9j\u00e0 demand\u00e9 comment les oiseaux parcourent des centaines ou des milliers de kilom\u00e8tres sans se perdre ?<\/strong><\/h2>\n\n

La r\u00e9ponse est due \u00e0 la magn\u00e9tor\u00e9ception, qui est un sens qui permet \u00e0 un organisme de d\u00e9tecter le champ magn\u00e9tique terrestre.Non seulement les oiseaux en sont atteints, mais aussi les arthropodes, les mollusques et les vert\u00e9br\u00e9s (poissons, amphibiens, reptiles, oiseaux et mammif\u00e8res). Le sens est principalement utilis\u00e9 pour l\u2019orientation et la navigation, mais il peut aider certains animaux \u00e0 former des cartes r\u00e9gionales.<\/p>\n\n

Comment les animaux peuvent-ils d\u00e9tecter le champ magn\u00e9tique ?<\/strong><\/h2>\n\n

Perception des animaux du g\u00e9omagn\u00e9tisme et des aimants<\/figcaption><\/figure>\n\n

Selon les chercheurs, les animaux peuvent d\u00e9tecter les champs magn\u00e9tiques en symbiose via les bact\u00e9ries vivant \u00e0 l\u2019int\u00e9rieur d\u2019eux (bact\u00e9ries magn\u00e9totactiques MTB), qui s\u2019orientent le long de lignes de champ magn\u00e9tique en raison d\u2019une cha\u00eene de structures magn\u00e9tiques \u00e0 l\u2019int\u00e9rieur de leur corps appel\u00e9es magn\u00e9tosomes.<\/p>\n\n
