Duurka ku magnetic of gariiradda la hadda ah. Electromagnets iyo codsigooda

Electromagnetism - set oo ah ifafaale sababa la xidhiidha ee hadda korontada iyo beeraha magnetic. Mararka qaarkood xiriirka waxay keenaysaa in Waxyeellooyin. Tusaale ahaan, hadda dal dhex maray fiilooyinka korontada doonni sababa wareegtaan markab aan loo baahnayn weecasho ee. Si kastaba ha ahaatee, korontada waxaa badanaa si ula kac ah loo isticmaalo si ay u abuuraan beeraha magnetic of xoojinta sare. Tusaale ahaan electromagnets ah. iyaga oo ku saabsan maanta iyo ayaan ka hadli doonaa.

hadda korontada iyo daadanayo magnetic

Xooggii uu duurka ku magnetic go'aan ka gaari kara tirada khadadka ka daadanayo magnetic, oo ku dhacda deegaanka unit. duurka ku magnetic meel walba ku dhacaa halkaas oo qulqulka hadda korontada, iyo ka daadanayo magnetic hawada saami la dambaysta ah. silig toosan siday hadda ah, in la wada xodan yihiin kartaa in gariiradda. At gacan ku filan yar yar ee jeedo, taasi waxay keenaysaa in la kordhiyo ka daadanayo magnetic. Xaaladdan oo kale, hadda waa la sii kordhisay.

Saamaynta fiirsashada istaagayn magnetic in la sii hagaajin karaa iyadoo la kordhinayo tirada markooda, ie. E. maroojinta silig in gariiradda. faqa waa run. The magnetic field gariiradda hadda waxaa lagu yarayn karaa hoos tirada markooda.

Waxaan soo dheegato xiriir muhiim ah. Halkaa marka ay marayso ee ugu badnaan cufnaanta ka daadanayo magnetic (waxaa halkii unit deegaanka Khadadka socodka ugu) xiriirka ka dhexeeya hadda korontada aan, tirada markooda ee xarigga n, oo ka daadanayo B magnetic waxaa lagu qeexay sida soo socota: In saami hadda V. 12 A, hadda ka dhex gariiradda of 3 markooda Waxay abuurtaa dhab duurka isla magnetic sida hadda 3 a, hadda ka dhex gariiradda of 12 markooda. Waxaa muhiim ah in la ogaado, xalinta dhibaatooyinka la taaban karo.

solenoid

gariiradda ee xarigga dhaawacaa, beer magnetic waxaa loo yaqaan solenoid ah. Xarkaha la dhaawacaa laga yaabaa on bir ah (core bir ah) ah. salka ku haboon iyo nonmagnetic (tus, core hawada). Sida aad arki karto, aad uma isticmaali karo oo keliya birta si ay u abuuraan gariiradda a magnetic field leh hadda. Eegaysana ee baaxadda core kasta oo aan magnetic ka daadanayo masaafada u dhigma. Taasi waa, xiriirka ka dhexeeya kor socodka hadda iyo tirada markooda ay dhacdo in this waxaa la sameeyaa si sax ah. Sayidka, duurka ku magnetic of gariiradda hadda waa la dhimi karaa, haddii aan codsan qaabkani.

Isticmaalka bir ah in solenoid ah

Waa maxay sababta in birta solenoid used? Its joogitaanka saamaysaa duurka ku magnetic of gariiradda la hadda laba eego. Waxa uu kordhiyaa saamaynta magnetic of hadda, inta badan kun oo jeer ama in ka badan. Si kastaba ha ahaatee, waxaa la jabin karaa mid dheellitirnaanta muhiim ah. Waxaa ku saabsan wixii jira ee u dhexeeya daadanayo magnetic iyo hadda in gariiradda la core hawada yahay.

beerta cqaadir ee domains bir (more hufan, oo ay daqiiqado magnetic) hoos tallaabada duurka a magnetic in ahbaa hadda loo dhisay in hal jiho. Sidaas darteed of joogitaanka core birta ah ee hadda ku soo daadanayo weyn magnetic halkii unit iskutallaabta qaybta fiilooyin. Sayidka, cufnaanta ka daadanayo oo aad u kordhiyaa. Marka dhan domains waafaqsan in hal jiho, sii kordhaya ee hadda (ama tirada markooda in gariiradda) wax yar oo kaliya kordhisaa cufnaanta magnetic ka daadanayo.

Haddaba idinku leeyahay wax yar oo ku saabsan induction ah. Tani waa qayb muhiim ah oo ka mid ah mawduucyo xiiso noo.

The gariiradda induction magnetic la hadda

In kasta oo duurka ku magnetic of solenoid la core bir ah waa badan ka xoog badan duurka ku magnetic of asaasiga ah hawada solenoid, miraheeda waa xadidan oo ay guryaha birta. Cabbirka gariiradda taas oo ah hawo-muhiimka ah aragti uu leeyahay xad lahayn. Si kastaba ha ahaatee, sida caadiga ah, waxay heli hadda wayn loo baahan yahay in la abuuro beer in uu u dhigmo in magnitude in gariiradda beerta la core bir ah, waa mid aad u adag oo qaali ah. Ha mar walba sidan u tagaan.

Maxaa dhacaya haddii aad bedesho duurka ku magnetic of gariiradda la hadda ah? Tallaabadan waxaa ay abuuri karaan koronto si la mid ah sida hadda u abuuraa beer magnetic. Marka u dhowaanin magnet si khadadka kaari xoog magnetic gudbaya kaari ah, xaadiriyaan goobaha danab a dhexdeeda. polarity ee danab ku laaluusheen waxay ku xiran tahay polarity iyo jihada isbedel aan istaagayn magnetic. saamayn Tan waxaa sii badan waxaa loogu dhawaaqaa in gariiradda badan in gariiradda gaar ah, waayo, kaasu waa saamiyeed si ay tirada markooda ee loogu fuuli jiray. In joogitaanka core bir ah danab ku laaluusheen in solenoid koror ah. Iyadoo habkan, kaari waa guurto ka daadanayo magnetic qaraabo. Haddii kaari uusan midaysan khadadka istaagayn magnetic, danab a kici doona.

Sida loo helo tamar

matoorrada Electric dhalin hadda ku salaysan mabaadiida isku mid. Sida caadiga ah, magnet waa wareegto dhexeeya gariiradda ah. magnitude ee danab ku laaluusheen ku xiran tahay xoog berrinkii magnet iyo xawaaraha (qeexo heerka of isbedel aan istaagayn magnetic). danab ee kaari waa si toos ah saamiyeed si ay xawaaraha daadanayo magnetic dhexdeeda.

In matoorrada badan magnet waxaa lagu bedelaa solenoid ah. In si loo abuuro beer magnetic of gariiradda la hadda ah, solenoid ku xiran yahay in ay il awoodeed. Taas oo ay dhacdo in this xoogga korontada soo saaray matoor ku? Waa loo siman yahay si wax soo saarka ee danab oo dhan hadda. Dhinaca kale, hadda ee kaari iyo xiriirka istaagayn magnetic ogolaanaya isticmaalka daadanayo ee ay hadda korontada oo duurka ku magnetic in ay soo saaraan mooshin farsamo. Sida ay mabda this, motor la socda iyo qaar ka mid ah qalabka korontada. Si kastaba ha ahaatee, si ay u abuuraan dhaqdhaqaaq ah oo aad u baahan tahay in ay qaataan awood dheeraad ah korontada.

beeraha Strong magnetic

Currently, iyadoo la isticmaalayo arrin ku superconductivity, waxaa suurtagal ah si ay u helaan xoogga aan horay loo arag ee gariiradda field magnetic leh hadda. electromagnets wuxuu noqon karaa mid aad u xoog badan. Marka ay tani hadda socodka m sameecadda ah. E. Ma keeni kululaynta mid ah waxyaabaha la. Tani waxay u ogolaaneysaa in aad dalbato walaac badan ee solenoids hawada-muhiimka ah oo ay ka fogaadaan xannibaad ay na saareen saamayn robab ah. rajada aad u wanaagsan ayaa shaaca ka qaaday gariiradda awood leh magnetic field leh hadda. Electromagnets iyo isticmaalkooda ma aha in aan micne lahayn saynisyahano badan oo xiiseynaya. Ka dib oo dhan, beer xoog loo isticmaali karaa dhaqdhaqaaqa "barkin" magnetic iyo abuurista nooc cusub oo matoorrada korontada iyo matoorrada. Waxay awood u ah wax soo saarka sare kharash yar.

tamarta oo ka mid ah magnetic gariiradda beerta hadda si firfircoon loo isticmaalaa by Dadka. Waxaa muddo dheer loo, gaar ahaan, on tareenka ee. Saabsan sida loo isticmaalo khadadka field magnetic of gariiradda la hadda ah loo xakameeyo dhaq-dhaqaaqa ee tareenada, hadda waxaan kala hadli.

Magnet on tareenka ee

System caadi ahaan loo isticmaalo on the tareenka, taas oo loogu talagalay electromagnets ammaanka weyn iyo magnet-joogtada ah waa kaabaha. Sidee shaqeyn karaan nidaamka? Strong magnet joogtada ah waxaa ku lifaaqan ku dhow yahay inuu tareenka ka fog qaarkood ka nalalka taraafikada. Inta lagu guda jiro marinka tareenka ka badan dhidibka magnet ee diyaarada magnet joogto ah cab darawalka ee la wareejiyo by xagal yar, oo korkoodana waxaa magnet weli boos.

Regulation ah gaadiidka tareenada ee

dhaqdhaqaaqa magnet guri ka mid ah gambaleelka ama seeriga. Next, soo socda dhacdaa. Ka dib markii laba qof oo ah darawal seconds cab gudba electromagnet ah, kaas oo la xidhiidha nalalka taraafikada. Haddii tareenka iftiimiyaa cagaaran, solenoid waa tamaraysan oo dhidibka of magnet joogtada ah ee gaariga la soo jeestay in ay markii hore, deminta alarm ee shidhka. Marka nalka taraafigga waa iftiin casaan ama jaalle ah, electromagnet la bakhtiiyey, ka dibna ka dib markii dib u dhac ah, toos ah u khusaysaa taayarada, dabcan, haddii ay halmaameen si uu darawalku. Jejebiyey circuit (iyo audio) waxa ku xiran shabakadda tan iyo markii dhidibka wareeg ah magnet ah. Haddii magnet inta lagu guda jiro dib u soo laabtay ay markii hore, ayuu kala jejebiyey aan loo firfircoonaan.
