Ndeipi remagineti?

Ndeipi remagineti? Kuti tipindure mubvunzo uyu, ngationei kuyeuka nheyo electrodynamics. Sezvo chikazozikamwa, uri mira inotakura mutariri Q, siyana wemagetsi mumunda nzvimbo rinowanika biasing kushanda nesimba F. The zvakawanda mutariri ukoshi (zvisinei zvivako zvavo), zvikuru simba. Makakatanwa Ichi - mumwe munda zvivako. Kana isu kunan'anura sechiratidzo E, isu zvino tora:

E = F / Q

Uyewo, mobile mhosva zvazvinoita remagineti hwezvisikwa. Zvisinei, muchiitiko ichi simba hakubvi chete pamusoro uwandu pamusoro yemagetsi muripo, asi pamusoro Vector kutungamirirwa rwokufamba (kana, kutaura zvazviri, nokukurumidza).

Tingaitei kudzidza configuration simba remagineti? dambudziko iri vakabudirira rwakapedza anozivikanwa masayendisiti - Ampere uye Oersted. Ivo inoiswa muitisi redunhu pamwe Magetsi zvakanyanya uye aongororwe migumisiro akaratidza. Zvakaitika kuti simba iri mugumisiro wacho gandiwa dzidziso iri muchadenga, zvichiratidza pamberi vektori achitaura torque. Induction simba remagineti (akayera mu Tesla) kunoratidzwa nhamba akati nguva simba kune zvibereko kondakita redunhu nzvimbo uye nekuyerera Magetsi. Kutaura zvazviri, rinotsanangura munda pacharo, iro hazvisi zvakakodzera. Patinorumbidza zvose akaudza kuburikidza nyore inonyatsoita:

B = M / (S * I);

apo M - kufadza kukosha torque kunoenderana dzidziso yacho loop ari remagineti; S - zvachose nzvimbo loop; I - kuitika munyika kondakita.

Sezvo remagineti ndiro imwe Vector yakawanda, zviri mberi kunodiwa kuwana dzidziso dzaro. The kupfuura ziso kumiririrwa rinopa tsono munhuwo Compass kuti nguva dzose anotaura kuchamhembe danda. Induction pasi remagineti orients zvichienderana remagineti mitsetse. Ndizvowo zvinoitika kana ukaisa nekambasi pedyo nemunhu kuburikidza iyo iyezvino Rwako.

Richirondedzera redunhu vanofanira kuunza pfungwa yacho rinobva nguva. Vector Izvi dziwande kuenzana zvibereko S kuti I. kutungamirira Its perpendicular kune notional ndege yacho conductive loop. Inogona pakutsvaga anozivikanwa rworudyi sikuruwa mutemo (kana thumbs kuti ndiye). Induction simba remagineti ari Vector mukufananidzira rinobatana kutungamirirwa rinobva pakarepo.

Saka, zvinobvira kuti zvinowana nzira yemaitiro nokuti simba kuita pamusoro loop (zvakawanda zvose Vector!):

M = B * M;

apo M - zvachose Vector nguva simba; B - rinobva induction; M - kukosha pakati rinobva nguva.

Zvakafanana dzinonakidza remagineti induction solenoid. Zviri humburumbira ane waya ronda pamwe izvo Magetsi inoyerera. Zviri ndeimwe kushandiswa zvinhu mune zvemagetsi mapurani. Muupenyu hwezuva nezuva, pamwe solenoids mumwe munhu anotarisana dzose nguva, vasingazivi nayo. Nokudaro, wakadenha ano remagineti mukati humburumbira iri zvachose homogeneous, uye ayo Vector chinotungamirwa coaxially chete humburumbira. Asi kunze humburumbira redzimba riri rinobva induction Vector ndisipo (razero). Zvisinei, ichi ichokwadi chete nokuda akakwana Coil pamwe husingagumi kureba. In tsika, muganhu yakasiyana. Chokutanga, kuti induction Vector hakusi kuenzana razero (munda wakanyorwa uye vakakomba humburumbira), uye munyika configuration uyewo anorasikirwa homogeneity kwayo. Sei, zvino, tinoda "muenzaniso yakanaka"? Very nyore! Kana asingasviki Kureba humburumbira dhayamita (Kazhinji), pakati solenoid induction Vector kushanda rinobatana ichi chinoratidza muenzaniso wakakwana. Kuziva dhayamita uye kureba humburumbira, zvinokwanisika kuverenga musiyano pakati yokupedzisira induction coils wayo akakodzera (magumo) ishamwari. It kunowanzoratidzirwa kuva chikamu.
