\u010co je magnet<\/h2>\n

magnet je objekt, ktor\u00fd vytv\u00e1ra magnetick\u00e9 pole, ktor\u00e9 pri\u0165ahuje ur\u010dit\u00e9 kovy ako \u017eelezo, nikel a kobalt. Toto magnetick\u00e9 pole je nevidite\u013en\u00e1 sila, ktor\u00e1 m\u00f4\u017ee pri\u0165ahova\u0165 alebo odpudzova\u0165 in\u00e9 magnetick\u00e9 materi\u00e1ly bez dotyku. Vo svojom j\u00e1dru magnetizmus vypl\u00fdva z pohybu elektrick\u00fdch n\u00e1bojov, najm\u00e4 z usporiadania elektr\u00f3nov v at\u00f3moch.<\/p>\n

Magnetick\u00e9 vlastnosti s\u00fa o tom, ako materi\u00e1ly reaguj\u00fa na magnetick\u00e9 polia. Niektor\u00e9 materi\u00e1ly, ako \u017eelezo, s\u00fa prirodzene magnetick\u00e9 a m\u00f4\u017eu by\u0165 trvalo magnetizovan\u00e9.

    Typy magnetov a ich pr\u00edklady<\/h2>\n

    Permanentn\u00e9 magnety<\/h3>\n

    Trval\u00e9 magnety si udr\u017euj\u00fa svoju magnetick\u00fa silu bez potreby elektriny. S\u00fa vyroben\u00e9 z materi\u00e1lov ako neod\u00fdm<\/strong>, ferit<\/strong>, a alnico<\/strong>. Neod\u00fdmiov\u00e9 magnety (tie\u017e naz\u00fdvan\u00e9 NdFeB) s\u00fa ve\u013emi siln\u00e9 a \u010dasto sa pou\u017e\u00edvaj\u00fa v elektronike a n\u00e1strojoch.

Alnico, vyroben\u00e9 z hlin\u00edka, niklu a kobaltu, sa pou\u017e\u00edva v mikrof\u00f3noch a niektor\u00fdch senzorech, preto\u017ee dobre dr\u017e\u00ed magnetizmus a odol\u00e1va teplu.<\/p>\n

    Elektromagnety<\/h3>\n

    Elektromagnety funguj\u00fa t\u00fdm, \u017ee cez dr\u00f4tov\u00e9 cievky zabalen\u00e9 okolo kovov\u00e9ho jadra prech\u00e1dza elektrick\u00fd pr\u00fad, \u010d\u00edm vznik\u00e1 magnetick\u00e9 pole iba pri nap\u00e1jan\u00ed. To znamen\u00e1, \u017ee m\u00f4\u017eu by\u0165 zapnut\u00e9 a vypnut\u00e9 pod\u013ea potreby. N\u00e1jdete ich v elektrick\u00fdch zvonkoch<\/strong>, zbera\u010dsk\u00fdch ramen\u00e1ch na skl\u00e1dke kovov<\/strong> ktor\u00e9 zh\u00e1\u0148aj\u00fa \u0165a\u017ek\u00e9 kovy, a MRI pr\u00edstroje<\/strong> pou\u017e\u00edvan\u00e9 v nemocniciach na zobrazovanie.<\/p>\n

    Do\u010dasn\u00e9 alebo m\u00e4kk\u00e9 magnety<\/h3>\n

    Do\u010dasn\u00e9 magnety, alebo m\u00e4kk\u00e9 magnety, si zachov\u00e1vaj\u00fa magnetizmus iba pri vystaven\u00ed magnetick\u00e9mu po\u013eu. Str\u00e1caj\u00fa magnetizmus r\u00fdchlo po odstr\u00e1nen\u00ed po\u013ea. Tieto magnety sa oby\u010dajne vyr\u00e1baj\u00fa zo slab\u00e9ho \u017eeleza alebo z podobn\u00fdch materi\u00e1lov. Uvid\u00edte ich v predmetoch ako transform\u00e1tory<\/strong>, relay-y<\/strong>, a in\u00e9 elektrick\u00e9 zariadenia, kde sa magnetick\u00e9 polia musia \u010dasto riadi\u0165 a meni\u0165.<\/p>\n
