Maginito kamwazi

Ntchito mphamvu mzere, osati tingasonyeze malangizo a m'munda maginito, komanso kuti mufotokozere ukulu wa kupatsidwa ulemu wake.

Tinakonza kuti agwire mizere ya mphamvu kotero kuti mwa 1 cm² m'dera perpendicular vekitala kupatsidwa ulemu pa mfundo ina, chiwerengero cha mizere unachitikira m'munda mphamvu ofanana pamalo amenewo.

Kumene mphamvu munda adzakhala wamkulu, mizere kumunda chachikulu. Tikawonetsetsa kumene mphamvu kumunda ndi kuchepa mphamvu mzere.

Choncho, osalimba a mizere maginito adzaweruzidwa pa kupatsidwa ulemu vekitala ake chikuperekedwa ndi malangizo a mizere ya mphamvu - za malangizo a vekitala lapansi.

Penyetsetsani wa mwachindunji panopa coils maginito makulidwe limasonyeza kuti kuchotsa kwa wochititsa ya maginito amachepetsa Komanso mofulumira kwambiri.

A maginito ndi kupatsidwa ulemu wosiyana pa mfundo zosiyanasiyana otchedwa sakanikira. Field ndi munda nonuniform ndi rectilinear ndi zozungulira panopa munda kunja solenoid ya m'munda wa maginito okhazikika , etc.

The maginito ndi chimodzimodzi pa mfundo zonse kupatsidwa ulemu ndi homogeneous kumunda. Zimaonetsa homogeneous maginito umaimiridwa ndi mizere m'munda oimira ofanana spaced kufanana mizere.

Chitsanzo cha munda yunifolomu ndiwo munda kwa mkati mwa koyilo yaitali, komanso m'munda pakati mosamalitsa-spaced kufanana planar nkhope mzati wa electromagnet lapansi.

The mankhwala a maginito ozama dera yogwira pa malo dera amatchedwa maginito kamwazi wa kupatsidwa ulemu maginito kapena kungoti maginito kamwazi.

Khama nampatsa ndi kuphunzira katundu wa sayansi English - Faraday. Iye anazindikira kuti mfundo imeneyi zimathandiza kuti tiganizire moposera za chikhalidwe logwirizana la zachilengedwe maginito ndi magetsi.

Kutanthauza kwa kamwazi maginito ndi kalata F, ndi mizere m'dera S komanso mbali pakati pa chitsogozo cha vekitala wa kupatsidwa ulemu B ndi N wachibadwa pa kuzungulira malo α, anthu aone kuti pali otsatirawa akhoza kulembedwa:

F = B S Ko α.

Maginito kamwazi - ndi kuchuluka scalar.

Popeza osalimba a mphamvu mizere ya m'munda umasinthasintha maginito liri kupatsidwa ulemu wake, ndi maginito kamwazi wofanana ndi chiwerengero lonse la mizere ya mphamvu mkatikati mwa dera yogwira.

Ndi kusintha m'munda ndi chimasintha kamwazi maginito zomwe likulowerera dera la: ndi amveke munda izo kumawonjezera pamene tithe kumvetsa kumasulira - amachepetsa.

Unit ya maginito kamwazi mu la SI analandira mtsinje umene likulowerera kudera la 1 m² ndi kukhala mu homogeneous maginito ndi kupatsidwa ulemu wa 1 WB / m², ndipo perpendicular kwa vekitala wa kupatsidwa ulemu. amodzi amenewa amatchedwa Weber

1 WB = 1 WB / m² ˖ 1 m².

Anasintha kamwazi ake maginito amapanga minda magetsi ndi mizere mphamvu atsekedwa (mmene kanyamaka magetsi kumunda). Pofunika limapezeka Windows Explorer ngati chinthu cha mphamvu yachilendo. zodabwitsazi amatchedwa mu atomu kupatsidwa ulemu, ndi mphamvu electromotive kwaiye pa nthawi yomweyo - EMF kupatsidwa ulemu.

Komanso, tisaiwale kuti kamwazi maginito limachititsa zimaonetsa wonse lonse maginito (kapena magwero a mphamvu ya maginito). Choncho, ngati maginito kamwazi kachulukidwe limachititsa zimaonetsa mmene nthawi imene mmodzi, kamwazi maginito - wonse. Ie, tinganene kuti ndi wachiwiri zofunika kwambiri khalidwe la maginito ilipodi. Motero, ngati maginito kamwazi kachulukidwe amachita monga mphamvu khalidwe la maginito, ndi kamwazi maginito - ndi makhalidwe mphamvu yake.

Tikaonanso zinachitikira, tikhoza kunenanso kuti iliyonse ya koyilo akhoza kulingalira ngati payokha wochimwa mwankhanza. Dera lomwelo, amene ndidzadutsa pa kamwazi maginito ya kupatsidwa ulemu maginito. Zikatero siidzasoŵa kupatsidwa ulemu magetsi. Choncho mchikakamizo cha maginito kamwazi kwaiye minda magetsi mu wochititsa chatsekedwa. Ndiyeno munda magetsi amapanga ndi magetsi.
