Bayani game da Magnetic Induction
Magnetic induction wani muhimmin abu ne na zahiri wanda ke da amfani mai yawa a fannoni daban-daban na fasahar zamani. Michael Faraday ne ya fara gano shi a ƙarni na 19 ta hanyar jerin gwaje-gwajen da suka canza yadda muke kallon makamashi da filayen maganadisu. A cikin wannan labarin, za mu yi bayani dalla-dalla game da menene magnet induction, yadda yake aiki, da aikace-aikacensa a aikace a fasahar zamani.
Fahimtar Shigar da Magnetic
Magnetic induction tsari ne da filin maganadisu zai iya samar da wutar lantarki a cikin na'urar jagora. Wannan yanayin induction ya ƙunshi hulɗa tsakanin filin maganadisu da na'urar jagora ta lantarki, wanda ke haifar da ƙarfin lantarki (EMF) ko ƙarfin lantarki. An kuma bayyana manufar asali ta induction ta hanyar Dokar Faraday ta Induction na Electromagnetic da Dokar Lenz.
An bayyana dokar Faraday a lissafi kamar haka:
\[ \mathcal {E} = -\frac{d\Phi}{dt} \]
inda \( \mathcal{E} \) shine ƙarfin lantarki, kuma \( \Phi \) shine kwararar maganadisu wanda shine samfurin filin maganadisu (\( B \)) da yanki (\( A \)) wanda layukan maganadisu na ƙarfi ke wucewa a wani kusurwa.
A halin yanzu, Dokar Lenz ta ba da alkiblar ƙarfin lantarki da aka haifar. A cikin mafi sauƙin tsari, Dokar Lenz ta bayyana cewa alkiblar wutar lantarki da aka haifar koyaushe tana samar da filin maganadisu wanda ke adawa da canjin kwararar maganadisu da ya haifar da shi.
Yadda Magnetic Induction Ke Aiki
Induction na maganadisu ya dogara ne akan canjin kwararar maganadisu akan lokaci. Akwai hanyoyi da dama na canza kwararar maganadisu, gami da:
1. Motsa Magnet a cikin Mai Gudanarwa: Ɗaya daga cikin hanyoyi mafi sauƙi don samar da wutar lantarki shine motsa maganadisu a cikin mai gudanar da karkace kamar na'urar waya. Yayin da maganadisu ke motsawa, layukan filin maganadisu suna ratsa mai gudanar da wutar, suna ƙara ko rage adadin kwararar maganadisu ta cikin na'urar kuma suna ƙirƙirar wutar lantarki.
2. Canza Ƙarfin Filin Magnetic: Idan ƙarfin filin maganadisu, \( B \), ya canza akan lokaci a cikin wani yanki, misali ta hanyar kunna ko kashe electromagnet, to kwararar maganadisu tana canzawa kuma wannan yana haifar da ƙarfin lantarki.
3. Juya Mai Gudanarwa a Filin Magnetic: Wannan shine ƙa'idar da ake amfani da ita wajen samar da wutar lantarki. Lokacin da aka juya mai jagora, kamar na'urar coil, a cikin filin maganadisu, yanayin mai jagora dangane da filin yana canzawa, yana haifar da canji a cikin kwararar maganadisu kuma yana samar da wutar lantarki.
Aikace-aikace a Fasaha ta Zamani
1. Na'urar Canza Wutar Lantarki
Na'urar canza wutar lantarki wata na'ura ce da ke canza matakin wutar lantarki a tsarin watsa wutar lantarki. Na'urorin canza wutar lantarki suna aiki ne bisa ka'idar shigar da maganadisu, inda canjin wutar lantarki a cikin na'urar farko ke haifar da ƙarfin lantarki a cikin na'urar ta biyu ta cikin tsakiyar ƙarfe.
2. Janareta Mai Lantarki
Janaretocin wutar lantarki suna amfani da na'urar magnetic don canza makamashin injiniya zuwa makamashin lantarki. Lokacin da mai jagora ya juya a cikin filin maganadisu, canjin kwararar maganadisu yana haifar da wutar lantarki a cikin mai jagora, wanda daga nan ake amfani da shi don aika wutar lantarki zuwa ga hanyar sadarwa ta wutar lantarki.
3. Injin Lantarki
Injinan lantarki suna aiki ne bisa ga ƙa'idar janareto. A cikin injin, wutar lantarki da aka shafa a kan na'urar naɗawa tana ƙirƙirar filin maganadisu wanda ke hulɗa da filin maganadisu mai tsayayye don samar da motsi ko ƙarfin juyi.
4. Shigar da na'urar lantarki a Sadarwa
Ana kuma amfani da fasahar lantarki wajen shigar da na'urorin lantarki a fasahar sadarwa, musamman a cikin eriya. Raƙuman lantarki suna haifar da kwararar wutar lantarki a cikin eriya masu karɓa ta hanyar shigar da na'urori, waɗanda daga nan ake mayar da su zuwa sigina da na'urorin lantarki kamar rediyo da talabijin ke amfani da su.
5. Tsaro da Ganowa
Tsarin kamar alamun RFID (Radio Frequency Identification) da fasahar hana sata a shaguna suna amfani da na'urar maganadisu don karanta bayanai ko gano abubuwa ba tare da hulɗa kai tsaye ba. Filin maganadisu daga mai karanta alamun ko firikwensin yana kunna alamar ko na'urar don aika siginar dawowa da ke ɗauke da bayanan shaida.
Tsarin Gwajin Magnetic Induction na Faraday
Michael Faraday ya gudanar da gwaje-gwaje masu yawa a cikin nazarin shigar da maganadisu. A cikin ɗaya daga cikin gwaje-gwajensa na ban mamaki, ya shirya na'ura kusa da maganadisu kuma ya lura cewa lokacin da aka canza filin maganadisu ta hanyar motsa maganadisu ko girgiza na'urar, wani emf da aka haifar ya bayyana a cikin na'urar.
Domin kwatanta wannan binciken, bari mu yi la'akari da na'urar waya da aka haɗa da na'urar galvanometer. Idan aka tura maganadisu a cikin ko kuma a fitar da shi daga na'urar, allurar galvanometer za ta motsa, wanda ke nuna cewa an haifar da wutar lantarki a cikin na'urar. Idan maganadisu yana hutawa a cikin na'urar, ba a tabbatar da cewa akwai wutar lantarki ba.
Faraday ya kuma ƙara haɓaka wannan ra'ayin ta hanyar wasu gwaje-gwaje, kamar amfani da na'urorin lantarki da ƙirƙirar kwararar wutar lantarki ta hanyar canza filayen lantarki tare da taimakon na'urori na biyu.
