Magnetic juyi

Amfani da ikon line, ba kawai za a iya nuna shugabanci na Magnetic filin, amma kuma ya faye hali da girma da ta shigar da.

Mun shirya zuwa ga gudanar da layin da karfi, don ta wurin 1 cm² yanki perpendicular shigar da vector a wani aya, da yawan Lines daidaita filin ƙarfi a wancan batu.

A wurin da filin ƙarfi zai kasance mafi girma, da filin Lines ne thicker. Conversely, inda da filin ƙarfi ne kasa da kasa ikon line.

Saboda haka, da yawa daga cikin Magnetic filin Lines suna hukunci a kan ta shigar da vector girma da kuma shugabanci na Lines na karfi - na shugabanci na vector.

Kallo na kai tsaye halin yanzu Magnetic a jere coils nuna cewa da kau da shugaba Magnetic filin rage-rage, haka ma, sosai da sauri.

A halin maganaɗisu filin tare da shigar da zalunci a daban-daban da maki kira iri-irin. Field ne nonuniform filin ne rectilinear kuma madauwari halin yanzu filin waje da solenoid, da filin na dindindin maganadisu , da dai sauransu

A halin maganaɗisu filin ne guda a duk wuraren shigar da shi ne kama filin. Graphically kama Magnetic filin wakilta filin Lines cewa wakilci daidai spaced layi daya Lines.

Wani misali da wani uniform filin ne filin da ciki na wani dogon nada, kazalika da filin tsakanin hankali-spaced layi daya planar iyakacin duniya fuskoki da electromagnet.

A samfurin na Magnetic filin iya shiga aiki kewaye a kan kewaye yankin da aka kira da Magnetic juyi na Magnetic shigar da ko kawai Magnetic juyi.

Tabbatar da dalilin ba shi da karatu da kaddarorin na Turanci likita - Faraday. Ya gano cewa wannan ra'ayi ya sa ya yiwu don kara la'akari da hadade yanayin da halin maganaɗisu da lantarki mamaki.

Denoting Magnetic juyi da wasika F, da kwane-kwane yanki S da kwana tsakanin shugabanci na vector na shigar da B da kuma al'ada n ga madauki yanki α, wadannan lissafi za a iya rubuta:

F = B S cos α.

Magnetic juyi - shi ne mai scalar yawa.

Tun da yawa daga karfi Lines na sabani Magnetic filin karkacewa ta shigar da, da Magnetic juyi daidaita dukan yawan Lines na karfi cewa, shiga cikin aiki kewaye.

Tare da canji a cikin filin da ya musanya Magnetic juyi wanda yake shiga cikin kewaye: da karawa filin ta ƙãra lokacin da loosening - tayi.

A naúrar na Magnetic juyi a cikin SI samu rafi wanda yake shiga wani yanki na 1 m² da kasancewa a cikin wani kama Magnetic filin tare da shigar da na 1 WB / m², kuma shi ne perpendicular zuwa vector na shigar da. Irin wannan naúra tana kira Weber

1 WB = 1 WB / m² ˖ 1 m².

Canjãwa ta Magnetic juyi ya haifar da wani lantarki filin da ciwon Lines na karfi ana rufe (vortex lantarki filin). Wannan filin bayyana a Windows Explorer a matsayin wani mataki na kasashen waje sojojin. Wannan sabon abu ne da ake kira electromagnetic shigar da, da kuma electromotive karfi generated a lokaci guda - EMF shigar da.

Bugu da ƙari kuma, ya kamata a lura da cewa a halin maganaɗisu juyi sa ya yiwu don faye hali overall dukan maganadisu (ko da wani sauran kafofin daga Magnetic filayen). Saboda haka, idan Magnetic juyi yawa sa ya yiwu a fahince ta sakamako a kowane daya batu, Magnetic juyi - a matsayin dukan. Watau, shi za a iya ce da wannan shi ne na biyu mafi muhimmanci halayyar Magnetic filin. Saboda haka, idan Magnetic juyi yawa abubuwa a matsayin ikon halayyar da Magnetic filin, Magnetic juyi - shi ne samar da makamashi halaye.

Mayar da kwarewa, muna kuma iya cewa kowane bi da bi na nada za a iya zaton a matsayin dabam dauka wani mugun nuna. A wannan rangadi, ta hanyar abin da za su auku Magnetic juyi na Magnetic shigar da. A irin wannan yanayi za a alama shigar da wutar lantarki yanzu. Saboda haka, shi ne a ƙarƙashin rinjayar Magnetic juyi generated lantarki filayen a cikin rufaffiyar shugaba. Kuma a sa'an nan zuwa wannan lantarki filin haifar da lantarki.
