Hogyan m\u0171k\u00f6dik az egyes t\u00edpusok<\/h4>\n

A permanens m\u00e1gnesess\u00e9g az anyagban l\u00e9v\u0151 rendezett m\u00e1gneses dom\u00e9nek eredm\u00e9nye. Ezek a dom\u00e9nek akkor is a hely\u00fck\u00f6n maradnak, ha a k\u00fcls\u0151 hat\u00e1s megsz\u0171nik. Ez az \u00f6nfenntart\u00f3 mez\u0151 azt jelenti, hogy az anyagnak nincs sz\u00fcks\u00e9ge \u00e1ramforr\u00e1sra.<\/p>\n

Az induk\u00e1lt m\u00e1gnesess\u00e9g ezzel szemben akkor k\u00f6vetkezik be, amikor egy norm\u00e1lisan nem m\u00e1gneses t\u00e1rgy m\u00e1gnesez\u0151dik egy m\u00e1gneses mez\u0151 k\u00f6zel\u00e9ben. A t\u00e1rgy csak addig marad m\u00e1gnesezett, am\u00edg ki van t\u00e9ve a mez\u0151nek. Ezt az elvet haszn\u00e1lj\u00e1k sz\u00e1mos elektromos alkalmaz\u00e1sban, p\u00e9ld\u00e1ul induktorokban \u00e9s elektrom\u00e1gnesekben.<\/p>\n

Permanens m\u00e1gnesek<\/span><\/a> kulcsfontoss\u00e1g\u00faak a m\u0171szaki tervez\u00e9sben. P\u00e9ld\u00e1ul, amikor dolgoztam motor szerelv\u00e9nyeken<\/span><\/a> kis elektromos j\u00e1rm\u0171vekhez, a megfelel\u0151 permanens m\u00e1gnes anyag kiv\u00e1laszt\u00e1sa jelent\u0151s helyet \u00e9s k\u00f6lts\u00e9get takar\u00edtott meg.

K\u00f6vetkeztet\u00e9s<\/h2>\n

A permanens m\u00e1gnesess\u00e9g id\u0151vel stabil marad k\u00fcls\u0151 hat\u00e1s n\u00e9lk\u00fcl, \u00edgy elengedhetetlen az elektronik\u00e1ban, a motorokban \u00e9s a napi eszk\u00f6z\u00f6kben.<\/p>\n
