Rinobva nekubudisa

Kushandisa simba mutsetse, kwete chete anogona kuratidza mirayiridzo remagineti, asiwo munguva kwakakura kwayo induction.

Takaronga kuita mitsetse simba kuitira kuti kubudikidza 1 cm² nharaunda perpendicular induction Vector pane imwe nguva, nhamba mitsetse vakabata wakaenzana munda simba panguva iyoyo.

Munzvimbo umo munda simba achava mukuru, munda mitsetse vari mukobvu. Ukuwo, apo munda simba riri shoma uye zvishoma simba mutsetse.

Nokudaro, arambe achirema pakati remagineti mitsetse vanotongerwa pamusoro wayo induction Vector nokukura uye mirayiridzo mitsetse simba - of achitungamirirwa vector.

Observation of rakananga ano rinobva spectra Coils kunoratidza kuti kubviswa muitisi remagineti zvinoderedza, uyezve, nokukurumidza kwazvo.

A remagineti pamwe induction dzisakarurama panguva dzakasiyana pfungwa anonzi heterogeneous. Field ari nonuniform Munda rectilinear uye dzeraundi ano munda kunze solenoid, munda ari wechigarire magineti , etc.

The remagineti ndiro zvachose pfungwa induction riri homogeneous munda. Yakanyatsotsanangura homogeneous remagineti hunomiririrwa munda mitsetse kuti zvinomiririra vakaenzana munzvimbo dzokuzororera dzaiva dzakafanana mitsetse.

Muenzaniso yunifomu munda ndiyo munda kuna mukati refu coils, uyewo munda pakati kunyatsotevera munzvimbo dzokuzororera dzaiva dzakafanana planar danda zviso electromagnet.

Zvinobikwa remagineti rakapinza basa redunhu iri mudunhu nzvimbo inonzi rinobva nekubuda pakati rinobva induction kana kungoti rinobva nekubudisa.

Kutsunga akamupa uye kudzidza zvivako of Chirungu yefizikisi - Faraday. Akawana kuti pfungwa iyi zvinoita kuti zvimwe funga vabatane zvakaita rinobva uye dzemagetsi mananara.

Anoratidza rinobva nekubudisa netsamba F, kuti gandiwa nzvimbo S, kundosvikazve pakona pakati vatungamirire Vector ose induction B uye inowanzotorwa N kuti loop nzvimbo α, zvinotevera mukana wokuti vanhu vanga anogona kunyorwa:

F = B S Kosi α.

Magnetic nekubudisa - chinhu scalar uwandu.

Sezvo arambe achirema kwesimba akarongwa zvemasanga remagineti akaenzana induction ayo rinobva nekubudisa akaenzana yose nhamba mitsetse simba kuti zvinopfuura zvinoshingaira vematunhu.

With kuchinja mumunda uye anochinja rinobva nekubudisa iyo chinopinda redunhu: iri amplification munda nayo anowedzera apo kusunungura - kunodzikira.

The chairema rinobva zvinoyerera ari SI vakagamuchira rukova iyo chinopinda imwe nzvimbo 1 m² uye ari munhu homogeneous remagineti pamwe induction 1 Wb / m², uye riri perpendicular kuti Vector kuti induction. chikwata kwakadaro anonzi Weber

1 Wb = 1 Wb / m² ˖ 1 m².

Ikachinja rinobva nekubudisa zvinowanisa wemagetsi munda une zvikonzero simba dzakavharika (vortex yemagetsi munda). munda uyu rinowanikwa Windows Explorer sezvo chiito mauto yokumwe. Fani iyi inonzi remagetsi induction, uye electromotive simba kwakaita panguva - EMF induction.

Uyezve, zvinofanira kucherechedzwa kuti rinobva nekubudisa runoita kuti munguva hombe magineti rose (kana zvimwe manyuko rinobva minda). Naizvozvo, kana simba rinonzi magnetic nekubudisa arambe achirema runoita kuti maitiro zvainoita chero imwe nguva, kuti rinobva nekubudisa - hwose. Kureva, zvinogona kunzi ichi ndicho chinonyanya kukosha cho mumwe remagineti wechipiri. Nokudaro, kana simba rinonzi magnetic nekubudisa arambe achirema anoita sezvo simba cho remagineti, kuti rinobva kokuyerera - ndiye simba raro unhu.

Achidzokera ruzivo, tinogona kutaura kuti ose kwezana coils inogona kufungwa somunhu oga akatora utsinye jana. The chete redunhu, kuburikidza icho achapfuura ari rinobva nekubuda pakati rinobva induction. Pakadaro zvichabviswa segwapa induction Magetsi. Saka, zviri pasi pokudzora rinobva nekubudisa zvakapararira minda yemagetsi iri namahwindo kondakita. Zvino uyu yemagetsi munda zvinowanisa magetsi.
