Rinobva induction

Tinoziva kuti magetsi-Kutakura kondakita Vakaisa remagineti, iri pasi ine simba. mirayiridzo yaro kunoenderana kutungamirirwa dzesango mitsetse uye mirayiridzo magetsi: kana ekupedzisira vanozivikanwa, vatungamirire simba kunogona tsunga nokushandisa kuruboshwe-ruoko utongi kana rworudyi sikuruu.

Ngatichiongororai chii chinoratidza kukosha simba iri. Achitaura chiitiko.

Suspension of rworuboshwe rocker mhikuriso anorwisa Linear kondakita AB muriise pakati matanda N uye S pamusoro electromagnet zvokuti perpendicular panyaya remagineti mitsetse. Nguva iri gwaro kuchasanganisira ammeter uye rheostat, nako unogona kuyera kuitika mune kondakita ichi. Zvienderane, uye dunhu iri namahwindo. Regai kuitika mu muitisi AB akatumwa kubva B kuti A. The pachiyero zviyereso kuputswa; kuti vaigadzirise, kurutivi mukombe kurudyi vachava kuisa imwe raznovesok ane uremu akaenzana simba anokonzerwa pamusoro waya vertically pasi. Isu achachinja pari zvino kondakita edu; tinoona kuti magetsi kuwedzera nekukura uye uto kuti chiito motokari. Changes achatiratidza kuti simba nako remagineti anoita muitisi ndiyo Proportional kuti inoyerera kuburikidza nayo magetsi zvakananga.

Zvinoenderana nokuti simba nokureba muitisi AB? Kugadzirisa nyaya iyi, isu ngaatore waya akasiyana urefu nenguva uno. Kuyerwa anoratidza kuti simba nako remagineti kunokanganisa magetsi-Kutakura kondakita, zvichava Proportional kuti urefu muitisi yaiva imwe remagineti zvakananga nesu.

Regai F - simba, iyo anoita pamusoro akatakura ano-kondakita Vakaisa remagineti, L - Kureba kondakita uye ini - iyezvino mairi.

With kuchinja paurefu L pamusoro kondakita uye kuitika mairi Anochinja, sezvataona, uye kwakakura simba F.

Nhamba simba F kuti urefu muitisi ano I uye kuramba pasina kuitika mariri; Naizvozvo, reshiyo ichi inogona munguva remagineti.

Izvi uwandu anonzi rinobva induction kana rinobva induction.

Kureva rinobva induction tsamba B. By tsanangudzo, mumwe anogona kunyora:

B = F / (I · l).

The SI chairema rinobva induction hurongwa anoita munda induction umo muitisi ane kwazvino 1 A uye 1 M refu iri pasi ine simba akadaro Name N. 1 chikwata: 1 Newton / (amper˖metr) (rakapfupikiswa 1 H / (AM)) .

We vanoti H 1 / (am) = 1 (V˖sek) / m²:

1 H / (am) = 1 (Shona) / (A˖m²) = 1 J / (A˖m²) = 1 (V˖A˖sek) / (A˖m²) = 1 (V s) / m².

Unit 1 volt-wechipiri ainzi Weber (Wb). Somugumisiro, 1 Wb / m² kana 1 tesla (T) - iri chairema rinobva induction. Kunyange zvazvo munyika yakayerwa emu chairema rinobva induction - gauss (G):

1 T = 10⁴ gauss.

Magnetic induction - Vector uwandu. Vatungamirire induction Vector panguva iyi dzichienderana kutungamirirwa simba rinonzi magnetic mitsetse achipfuura pfungwa iyi.

The SI rinobva nekubudisa arambe achirema - simba munda rinobva hunhu, zvakafanana sei yemagetsi munda anoratidza simba cho yemagetsi munda.

Kuziva induction remagineti, zvinokwanisika kuverenga simba pamusoro magetsi-Kutakura muitisi maererano fomura:

F = Bi l.

Mune kuitika-Kutakura kondakita kwete chete mhosva vanotama randomly kwakasiyana-siyana, asi mune zvimwe zvokuita. Mumwe nomumwe mhosva kunokanganisa rinobva simba iri chakasvitswa muitisi. Verengai varwi vose kubva runobva inofamba iri razero, uye uwandu hwehondo rinotungamirirwa sangano rinonzi Ampere simba.

Kazhinji, uwandu simba iyo anoita magetsi-Kutakura kondakita Vakaisa remagineti pakutsvaga Ampere mutemo:

F = Bi L chivi α, sezvamakaropafadzwa α - pakona pakati magetsi mirayiridzo (I) uye simba remagineti Vector (B).

remagineti induction ndiyo dziwande akaenzana simba hunovhiringidza remagineti paminiti chikwata ano maatomu akafanana dzinongoda perpendicular kuti Vector kuti induction. Magnetic induction kwakavakirwa zvenhau ehupfumi.
