Chii Eddy dzenzvimbo?

Electricity tichigara kwete chete mukugadzira asiwo muupenyu hwezuva nezuva. Munhu anogona kunyange kuziva kuti Eddy dzenzvimbo kwakadaro, asi basa vakaita, zvakatarisana zuva nezuva. Somuenzaniso, vanhu kubvira kare kuti magetsi nokungoita vachisundira chinja bhatani, pasina kufunga pamusoro pezvakaitwa zvinobatanidzwa. Izvozvo ndizvo zvakaitika iyi. Saka, kunzwisisa zvakavanzwa pasi rokuti "Eddy Eddy dzenzvimbo" uye kuona mashandiro pakati panowanikwa kwavo, zvinokosha kuyeuka zvechadenga Magetsi. Asi kutanga, isu kupindura mubvunzo "sei Foucault?"

Nokuti kokutanga Eddy dzenzvimbo dzave vanotaurwa zvakanyorwa yefizikisi French Arago D. F. Iye akataura vatorwa maitiro pemhangura Disc, apo akanga akaisa kutenderera magnetized tsono. Pasina chikonzero chakajeka, Disc anotanga tenderera pamwe kutenderera museve. Panguva iyoyo (1824) tsanangura maitiro ichi vachigere, saka, kutanga rinonzi "chinonakidza kuti Arago." Makore mashomanana gare gare, mumwe musayendisiti - Michael Faraday, achishandisa Chiitiko kuti Arago kwakaita Kuwanikwa mutemo pakati remagetsi induction, chasvika mhedziso kuti ichi kana inofamba iri Disc hunogona kungoparara kutsanangurwa nemashoko ari Act. Maererano yaida tsananguro, iri kutenderera remagineti anoita muitisi maatomu (mhangura dhisiki) uye anoita achitaura kufamba mhosva (inobudisa) nezvimedu marongerwo. Mumwe zvivako zviri Magetsi ndechokuti kumativi muitisi tiine remagineti. Predictably, uye Eddy dzenzvimbo kubereka munda wavo interacts pamwe huru, ivo generating. Shoko "vortex" rinotsanangura nzira kugoverana dzenzvimbo kudaro kondakita: mirayiridzo yavo electrically kunofambidzana. Zvichienderana basa Arago uye Faraday, Eddy dzenzvimbo vanenge vadzidza Foucault yefizikisi. Nokudaro, kunoguma zita.

dzenzvimbo izvi hadzisi akasiyana zvikuru kubva induction zvinoberekwa jenareta. Kana paine vortex remagineti (rakatumbuka, kutenderera) uye nemunhu pedyo, zvino nokuda kuitwa remagetsi minda vafurira dzenzvimbo. The makuru uye bulkier muitisi, dzakanga kuitika ukoshi iri kunotangira dzenzvimbo. Uyezve, Eddy dzenzvimbo nguva dzose pave remagineti kuti anodzivisa kuchinja chekubuda. Sezvo magazini kuwedzera, zvinokonzera pakaunda-electromotive simba apo mukuderedza kudaro, Eddy ano munda anoramba huru chokubuda. The kumusoro kunofanira kuva mutemo Lenz.

Zvechokwadi havagoni kutaura, anobatsira kana kunokuvadza Eddy dzenzvimbo kuti mune zvimwe zviitiko, vari sechinoitika anowedzeredza uye zvakasiyana rwokugadzira mhinduro kuderedza navo, vamwe, nekusiyana, kudiwa ndizvo chaizvo ehupfumi pamusoro dzenzvimbo idzi. Mumwe mukomana kuongorora kamwe deciphered kukandwa transformer. Chinoumba (hwaro pamusoro iyo windings vari muchikuvadza) haisi nguva dzose kuumbwa chinokosha, uye inounganidzwa kubva vakawanda matete mahwendefa rinobva simbi (ainzi laminated). Zvese pamusoro nemamiriro ndiro akafukidzwa ane insulating lacquer uye akabika nokuda yakachengeteka kubatana. Dzimwe nguva Musimboti mberi chibvumirano yoga Pin. Kwakadaro kuomesa kuvakwa kwakamutsa: zvakakodzera substantially kuderedza Eddy dzenzvimbo ari core. Zvechokwadi, sezvo yave akati, kashoma hombe muitisi, iyo yakakura kuramba yemagetsi mudare nayo ane.

Mune zvimwe zviitiko, vamwe zvivako zviri Eddy dzenzvimbo dziri kudiwa. Somuenzaniso, basa induction yamavira inobva kudziyisa kondakita ndiyo hombe mugumisiro Eddy dzenzvimbo vakafurira chinokosha jenareta. Uyezve, vari kushandiswa kuona pamberi imperceptible deffektov ari simbi mamiriro.
