Ferrofluid

In ka sagaashankii hore ee qarnigii la soo dhaafay yimid filimka "Terminator 2" on screens shineemada. All daawadayaal ah ayaa la dhacay qaab ciyaareedka biraha ductile dilaaga cyborg awoodda, ciyaaray by Robert Patrick, qaado noocyo kala duwan oo guises.

Markaas, maxfalka animation ee computer xirfad ka dhigtay, ma waxaan u malaynayaa in oo ku saabsan xaqiiqada ah in saamaynta waa fantastic transformations cyborg-dilaaga la Yururb kartaa in xaaladaha nolosha dhabta ah.

Ferrofluid - taasi waa wax kuu oggolaanaysa in aad aragto farshaxan dhaqaaqin. By ay classical field magnetic la soo jiidatay karaa ama ku eeliyey walxaha dhan. Laakiin falcelinta ee ugu iyaga ka mid ah waa sidaas oo daciif ah in ay keliya lagu ogaan karaa by alaabtii gaar ah. Waxay noqonaysaa fiican haddii aad kor ugu qaadi karo sifooyinka magnetic of qalabka oo aan ku baabbi'iyo ay qaab-dhismeedka iyo isbedel aasaasiga ah ee guryaha bilowga ah ay.

Wax walba bedelay markii in xalka dhibaatada this farageliyey farmashiye iyo abuuray dheecaan ferromagnetic, isagoo flowability wanaagsan. Waxay suurtagashay in ay hesho qayb yar magnetic kaas oo la soo bandhigay galay dareeraha, oo markii loo feydo beeraha magnetic ma dhumiyaa banooni iyo waxa aan la degay, iyo dareere la sameeyo "adag".

dheecaan Ferromagnetic - firidhsan ah Kolloidol ee ferrites, qalabka ferromagnetic la qayb aad u yar degto ee dhexdhexaad ah aqueous ama shidaalka, oo walxaha shaqaynayaa taageero dusha. dheecaannada noocan oo kale ah waa mid deggan dhowr sano oo ay leeyihiin sidaas flowability wanaagsan weheliso guryaha magnetism.

dheecaan Ferromagnetic waxaa laga heli karaa siyaabo badan. Geedi socodka waa caddaalad ah oo fudud oo ka kooban tahay laba marxaladood. Marka hore, loo baahan yahay si ay u helaan qayb ka magnetic la cabbir u dhow Colloid ah. Oo anigu waan ka badan - si ay u xasilin in saldhig dareere ah.

Aad mawduuc khuseeya cilmi waa wax macquul ah ee codsiga wax ku ool ah oo cabitaanno ah sida. Sanadihii la soo dhaafay, ay u shaqeeyaan on biyaha lagu nadiifiyo qashinka dareeraha sida saliid. Mabda'a geedi socodka this - magnetization saliidda by sal-dhigida oo cabitaan ah magnetic in biyaha daata ee. Oo markaas saliid magnetized kala nidaamyo gaar ah.

dheecaan Ferromagnetic helaa codsiga ee daawada. Tusaale ahaan, daawooyinka anticancer Dhibayn unugyada caafimaadka qaba. Laakiin haddii aad isku daraan daawada oo dareere ah iyo saaray bukaanka ku jira dhiigga iyo in burada looga samatabbixiyo magnet ah, ka dibna isku dar ah waa mid isku urursan meel sax ah oo aan waxyeello jidhkaaga oo dhan.

Oo halkan tusaale kale. Shirkadaha soo saara baabuurta tartanka, bambarro ku daadiyeen ferrofluid. Guuldareystay iyaga electromagnet isla dhigaysa dheecaanka dareere ama viscous. Sayidka, ganaax gaariga beddelo.

Waxay leeyihiin dareere sida iyo guryaha cajiib ah. Haddii aad ka maqnaan la ruxruxo codka iyada oo dareere ah magnetized, in gariiradda ah yeelista, ku yaalaan soo socda in ay ciidamo driving korontada. Oo kale. Haddii xalka goobooyin ku dar dareeraha ah magnetic, waxaad ka heli aragti xiiso.
