Diamagnetski vs Paramagnetski<\/h1>\n

Da li zna\u0161 da se svi materijali ne pona\u0161aju isto u magnetskom polju? Neki se privla\u010de, drugi se odbacuju. Hajde da istra\u017eimo za\u0161to.<\/p>\n

Razlika izme\u0111u diamagnetnih i paramagnetnih materijala le\u017ei u njihovoj magnetnoj osjetljivosti i na\u010dinu na koji reaguju na spolja\u0161nja magnetska polja.<\/strong><\/p>\n

Oboje tipovi imaju klju\u010dne uloge u nauci i tehnologiji\u2014razumevanje njihovog pona\u0161anja poma\u017ee pri izboru materijala za magnete, senzore i za\u0161titu.<\/p>\n

Koja je razlika izme\u0111u diamagnetnog i paramagnetnog magnetskog polja?<\/h2>\n

Stavlja\u0161 dva materijala u isto magnetsko polje. Jedan se kre\u0107e ka njemu, drugi se kre\u0107e od njega. \u0160ta se de\u0161ava?<\/p>\n

Paramagnetni materijali su slabo privu\u010deni spolja\u0161njim magnetskim poljima, dok su diamagnetni materijali blago odbojani od njih.<\/strong><\/p>\n

Razumevanje fizike koja je iza toga<\/h3>\n

Hajde da uporedimo osnovne karakteristike:<\/p>\n\n\n\n\n\n\n\n\n\n\n

U mom dnevnom radu sa magnetnim sklopovima, video sam da kupci gre\u0161kom biraju bakar (diamagnentan) kada su o\u010dekivali pove\u0107anje polja \u2014 na kraju je \u0161titio magnetsko polje umesto da ga poja\u010da. Zato biranje pravog tipa ima zna\u010daj.<\/p>\n

Koje je vi\u0161e magneti\u010dno, paramagnetno ili diamagnetno?<\/h2>\n

Ako uporedimo ova dva, koje pokazuje vi\u0161e \u201cmagnetizma\u201d?<\/p>\n

Paramagnetski materijali su magnetski sna\u017eniji od diamagnetnih jer su privu\u010deni spolja\u0161njim magnetskim poljima, dok su diamagnetni materijali odbojni.<\/strong><\/p>\n

Pore\u0111enje magnetne snage i korisnosti<\/h3>\n

Paramagnetski materijali imaju neparne elektrone, koji se uskla\u0111uju sa magnetnim poljima \u2014 iako je efekat mali. Ovo pona\u0161anje ih \u010dini korisnim u oblastima poput MRI i magnetnog senzora.<\/p>\n

Diamagnetni materijali, s druge strane, otporni su na magnetno polje. Oni stvaraju polje u suprotnom smeru, \u0161to dovodi do odboja. Ovaj efekat je jo\u0161 slabiji, ali je stabilan i predvidljiv \u2014 savr\u0161en za magnetno \u0161titenje i eksperimente sa levitacijom.<\/p>\n\n\n\n\n\n\n\n\n

U jednoj primeni senzora u avijaciji, preporu\u010dio sam prelazak sa mesinga (uglavnom diamagnetski) na aluminijum (paramagnetski) kako bih postigao suptelan ali dosledan porast polja. Promena je pobolj\u0161ala jasnost signala za 12%.<\/p>\n

Zaklju\u010dak<\/h2>\n

Diamagnetski materijali odbijaju magnetska polja; paramagnetski materijali postepeno se privla\u010de. Jedan \u0161titi, drugi pobolj\u0161ava. Izbor pravog mo\u017ee da odlu\u010di va\u0161 dizajn.<\/p>\n
