Magnetismus je z\u00e1kladn\u00ed s\u00edla, kter\u00e1 vznik\u00e1 pohybem elektrick\u00fdch n\u00e1boj\u016f.

J\u00e1drem magnetismu jsou atomy, kde se elektrony pohybuj\u00ed a ot\u00e1\u010dej\u00ed, vytv\u00e1\u0159ej\u00edc mal\u00e9 magnetick\u00e9 pole.<\/p>\n

\"Magnetick\u00e9<\/p>\n

Magnetick\u00e9 materi\u00e1ly se chovaj\u00ed odli\u0161n\u011b v z\u00e1vislosti na jejich atomov\u00e9 struktu\u0159e a zp\u016fsobu, jak\u00fdm jejich elektrony interaguj\u00ed s magnetick\u00fdmi poli. T\u0159i hlavn\u00ed typy magnetismu jsou diamagnetismus<\/strong>, paramagnetismus<\/strong>, a feromagnetismus<\/strong>.<\/p>\n

Diamagnetismus<\/strong> nast\u00e1v\u00e1, kdy\u017e materi\u00e1l vytv\u00e1\u0159\u00ed mal\u00fd magnetick\u00fd moment, kter\u00fd odporuje aplikovan\u00e9mu magnetick\u00e9mu poli. Tento efekt je velmi slab\u00fd, proto\u017ee poch\u00e1z\u00ed ze zm\u011bn v ob\u011b\u017en\u00fdch drah\u00e1ch sp\u00e1rovan\u00fdch elektron\u016f.

Paramagnetismus<\/strong> vyskytuje se u materi\u00e1l\u016f s nep\u00e1rovan\u00fdmi elektrony. Tyto nep\u00e1rovan\u00e9 elektrony vytv\u00e1\u0159ej\u00ed mal\u00e9 magnetick\u00e9 momenty, kter\u00e9 se slab\u011b slad\u00ed s vn\u011bj\u0161\u00edm magnetick\u00fdm polem, co\u017e zp\u016fsobuje m\u00edrn\u00e9 p\u0159itahov\u00e1n\u00ed.

Feromagnetismus<\/strong> je nejsiln\u011bj\u0161\u00ed magnetick\u00e9 chov\u00e1n\u00ed. Zde se magnetick\u00e9 momenty atom\u016f spont\u00e1nn\u011b slad\u00ed ve stejn\u00e9m sm\u011bru, i bez vn\u011bj\u0161\u00edho pole. To vytv\u00e1\u0159\u00ed trval\u00e9 magnety. B\u011b\u017en\u00e9 feromagnetick\u00e9 materi\u00e1ly jsou \u017eelezo, kobalt a nikl. Jejich siln\u00e1 magnetick\u00e1 vlastnost je kl\u00ed\u010dov\u00e1 v mnoha odv\u011btv\u00edch, zejm\u00e9na v elektronice, motorech a magnetick\u00e9m ukl\u00e1d\u00e1n\u00ed.<\/p>\n
