Maandooriyaha duurka a magnetic. dhexgalka field magnetic la maalkii

Imisa ifafaale la sharrixin oo qarsoon xallin qarin dhulkeenna! Laakiin dadkii degganaa dhawrid Earth ka mid qarnigii inaad wax ka barato sharciyada, si ay u tijaabiyaan, Been, gebagebo oo isticmaalaan waxay Been Abuuran. Secrets of Cosmos iyo dabeecadda si joogto ah yeedhi dadka, iyaga riixaya oo dhan tijaabo cusub ee raadinta runta iyo furayaasha. Mid ka mid ah waxyaalaha qarsoon oo waa dabeecadda walax duurka a magnetic.

Galku ugu horeysay magnetic

Sida laga soo xigtay halyeeygii hore ee, adhijir qadiimiga magacaabay Magnus mar ogaadeen in uu shaqaalaha ku xayiran in ay dhinaca biraha dhagaxa. Waxa uu (dhagax) iyo waxaa ka go'an in daahfurka. Sida ay aragti kale, erayga "magnet" la luqada Giriigga macnaheedu yahay "dhagax ka magnesia", magaaladii magnesia, halkaas oo beeraha magnetic ayaa laga helay ka dib. Xitaa dhowr boqol oo BC, Chinese ah ayaa ogaaday in qaar ka mid ah dhagaxyada ayaa waxaa wada qabtay in sidan oo kale ay tahay in si xor ah isku shaandheyn karaa, si joogto ah u soo jeesan jiho gaar ah.

Sidee u wareegtaan

The ugu horeysay ee baraheeda xarooda of qaaddo magnetite ul yar oo la isku beddeli karaa goobada. Muddo ka dib, ka dib markii jeestay qaadada, ayay joojiyeen, iyo xudunta ayaa had iyo jeer tilmaamay xagga woqooyi. Laakiin ciidamada, kuwaas oo si yar si ay isku shaandheyn karaa oo kaliya u wareegtaan Itoob ku lifaaqan yihiin.

baxriyiintii Later geliyo irbad magnetic in kale caws ah oo ku rid baaquli biyo. Straw mar walba waxay muujinaysaa jihada woqooyi - koonfureed. Sababta tani, ifafaale ka dibna weli sahamin - nooc ka mid ah beerta ku wareegsan dhulka, taas oo uu leeyahay awood u leh inay saamayn walxaha ku dhex jira, iyo loo ogaado in ay jihada.

gudbikaraa magnetic ku wareegsan dhulka

Our Earth waa-celiska ah laga wareejiyey, kaas oo u shaqeeya Ciidamada magnetic, ay magaca - duurka ku magnetic. Inkastoo version ee asal ahaan waxaa ka mid ah aan la xaqiijiyay, laakiin Geophysics asal ahaan raacsan tahay war ah in uu jiro beer magnetic ay sabab u tahay halabuurka ee muhiimka ah birta of our meeraha. wareeg ee Dhulka kordhinayaan in formation of core macdan la shubay socodka joogtada ah ee lagu eedeeyay korontada, kuwaa oo kor u polya.Zemlya magnetic ku wareegsan, sidaas simaha magnet weyn, kuwaas oo jawaab celin iyo baraheeda.

Guryaha iyo dabeecadda magnet-ka

Magnet, sida kuwa jecel in ay qurxiyaan qaboojiyaha ama qaban note ah jikada, waxay leeyihiin guryaha halkii xiiso leh. dhaqanka ee walxaha beer magnetic waxay ku xiran tahay waxyaabaha ay ka koobanahay walxaha kuwan. Qof walba waa ogyahay in magnet eekaan bir ama birta shayga. Oo maxaa waxyaalahan oo dhacdo? magnet kastaa waxa uu leeyahay laba ulaha. Haddii aad tijaabo ah oo sii labo ka mid ah magnet-dhow ee soo socota in kasta oo kale, waxaa soo baxday in pole woqooyi mid soo jiidata soo horjeeda - koonfureed - cirif ee kale. Si kastaba ha ahaatee, haddii aad la geeyo ee birlabta pole isla, waxay had iyo jeer kada doonaa mid kasta oo kale. Electrons, taas oo daba noqonayaa nuclei eb waxay leeyihiin amar diidmo korontada. webigu ku soo qayb eedeeyay saarta beer magnetic in sara kacaba siddo badan oo ku wareegsan.

Tusaale ahaan, goortii ilayska waxaa loo shiday, hadda korontada maraa ay taararka, iyo electrons u guurto mid ka mid eb in kale, iyo hareeraha taararka soo baxdo beer daciif magnetic. Sidoo kale, a beerta magnetic xoog leh ka fiilooyin danab sare socda. Korontada iyo magnetism jira laba qaybood u dhaqmaan sida electromagnetism. electron kasta wareegi hareeraha dhidibka sida meeraha ah in jirsado ay falagiisuu la dhiso loop a yar oo hadda korontada abuuraa beer magnetic in ay walax. Maandooriyaha duurka a magnetic u dhaqmaan si ka duwan.

Sidee dhexgalka garoonka magnetic la maalkii

Tusaale ahaan, ka yar tallaabada duurka magnetic dhacdaa on caag ah waxaa ka mid ah beerta Ghadafi magnetic of kasta oo atamka ee midba midka kale uga takhalusi lahaayeen, maxaa yeelay, ulaha ay si toos ah in jiho oo kala duwan. Laakiin atamka birta waxaa lagu abaabulaa sida in maaddadu ay tahay awood la magnetized. atamka ku jira waxay la soo ururiyay ee kooxaha iyo waxaa loo yaqaan domains magnetic. domain kasta oo yar oo ka kooban yahay balaayiin qurubyada la beeraha oo dhan ay magnetic, kuwaas oo isku jiho ah, iyo isu magnet yar noqdo. jejebiyey birtii isu Domains ku fiiqaya in jiho oo kala duwan, si ay u midba midka kale baajiso, oo madax banaan oo bir ah ma muujiyaan guryaha magnetic. In la abuuro magnet ah oo dhan domains waa in la ku yaal hal jiho, ka dibna xoogaa yar oo bir ah si magnetize oo soo jiitay dhammaan alaabta birta ah ee u dhow. Sida loo sameeyo birta domains taagan yahay si la mid ah? Si fudud: waa in xoogaa yar oo bir ah ku riday duurka ku magnetic. Diyaarineysa mid ka dib markii kale ee, domains waxaa la geeyay dhinaca duurka jooga. Oo saasna waxay u soo jiidan doonaa atamka ee domains kale, sii kordhaysa ee size.

Si dhakhso ah, qaar badan oo ka mid ah walxahaasi abuuri doonaa line a, iyo xoogaa yar oo bir ah laftiisa uu noqonayaa magnet ah soo jiidan doonaa laftiisa in pin, ciddiyaha ama biraha kale shay kasta oo goobta joogay. Sidaas waxaa jira magnetization duurka ku magnetic ah waxyaabaha ku jira aad buu u badiyey. Laakiin sida ay yidhaahdaan, si fiican si aad u aragto mar ka badan maqli jeer boqol. Waa laga reebo lahayn, waxaana baadhaya ugub ah. Sidee si ay u hubiyaan in la yidhaahdo?

duurka ku magnetic iyo magnetization ee maadooyinka la oran karo waa, tusaale ahaan in guriga. Waa ku filan tahay si ay u qabtaan waayo-aragnimo fudud. Qaado dhidib bir yar oo ku dhejiyey qaboojiyaha la magnet ah. domains uu saf ugu jira si dhakhso ah, oo in muddo ah ciddiyaha laftiisa noqon doonaa magnet ah, taasi oo ka kaas oo waxa ay noqon doontaa fudud si ay u kor pin ah.

Determination of duurka ku magnetic

Si aad u barato duurka ku magnetic ee wax bartay laba nooc oo hadda - makrotoki iyo micro. Makrotokami kuwa abuuray mooshinka ka mid ah meydadka sheybaarada eedeeyay. Microcurrent yeedhay hadda by dhaqaaqin electrons in atamka, taagoo iyo udhigo. duurka ku magnetic in wax ka si ay u abuuraan labada beeraha: makrotokami dibadda abuuray iyo gudaha - microcurrent sameeyay.

walax magnetic Most

Dhab ahaantii xiiso leh waa in ee dabiiciga ah waxaa jira magnet dhab ah - lodestone macdanta ah. Laakiin bulk of meydadka ay duurka ku magnetic gaar ah, weli kiimikaysan abuuray by nin. The ugu xoogga badan oo ka mid ah waa kuwa u taagan daawaha ee neodymium, bir iyo boron. Waa maxay maalkii magnetic maanta? Qubarada waxa ay ka jawaabto su'aashan awoodaan. physicists Group ka Minnesota abuuray wax cusub oo ka kooban 16 atamka bir ah iyo 2 atamka nitrogen, taas oo ah waxa lagu gartaa permeability magnetic waa 18% ka sarreeya in ka mid ah ugu awooda badan - neodymium - magnet.

Waa maxay magnet-ka

duurka ku magnetic in wax ka, ee gaaban, waxay ku xiran tahay magnet-ka. Habeynta kasta oo iyaga ka mid ah oo duurka ku ah magnetic abuuraa ay duurka ku magnetic in arrinta. Noocyada magnet waxaa soo socda: qalabka diamagnetic, paramagnetic iyo ferromagnetic. The beeraha ugu awooda badan abuuro ferromagnets, maxaa yeelay, waxay leeyihiin guryaha magnetic sare. walxaha noocan oo kale ah waxaa ka mid ah birta, nickel, cobalt, macdanaha dhulka dhif iyo Alloys ay, iyo sidoo kale chromium iyo Alloys manganese. Of iyaga ka dhigi magnet-joogto ah, sababtoo ah berrinka ferromagnetic ma baabi'i ka dib markii la joojiyo oo duurka ku magnetic.

Paramagnetic hantidaan permeability taas oo in yar ka sarreysa midnimada heerkulka qolka. walxaha noocan oo kale ah in beerta a magnetic magnetized xun, laakiin hoos u heer-kulka, guryaha magnetic iyaga ka mid ah ayaa kor u. By paramagnet waxaa ka mid ah, tusaale ahaan, oxygen, platina, aluminium, dhulka dhif ah biraha.

Diamagnetics - nooc kale ee wax, permeability ee taas waa wax yar ka yar midnimada, guryaha ay magnetic xataa taagta daran. Si aad kuwa falan Biraha badan sida bismuth, lacag, iyo dahab, copper, iyo sidoo kale biyaha iyo xeryahooda organic. Dhab ahaantii xiiso leh in guryaha ferromagnetic baaba'aan, iyo birta iyo noqdo paramagnetic demagnetized markii kululeeyo si a heerkulka gaar ah (hal dhibic Curie).

Isticmaalka beer magnetic

Dadka bartay in ay isticmaalaan si ay faa'iido ah guryaha ku xusan mid ah waxyaabaha la duurka a magnetic: ferromagnets waa lagama maarmaan in soo saaridda of injineernimada korontada iyo computer. Waxay waxaa laga heli karaa gudbiyeyaasha, matoorrada, iyo aaladaha cabbiraadda kala duwan, ay oggolaadaan in aad si loo kordhiyo duurka ku magnetic oo aan badalayn hadda in gariiradda.

ciidamada qalabka sida si weyn hoos ugu dhigi kartaa isticmaalka awoodda. Waxay waxaa loo isticmaalaa lagu qoro magnetic iyo kormeerka, labiska ore. Maalmahan daawo isticmaalaa magnet ee baaritaanka iyo daawaynta cudurada kala duwan. Asal ahaan, shaqada qalabka ogaanshaha ku salaysan yahay tallaabo oo ka mid ah magnet-joogta ah. Tusaale ahaan, tilmaame tonometer indhaha ah u baahan yahay in la ogaado glaucoma marxalad hore. Waxaa loo adeegsaday in qalliin iyo microsurgery, qalabka magnetic ka guurtaa oo bir ka goosin ka mid ah aadanaha. Ay mabda 'hawlgalka ayaa waxaa sidoo kale ku salaysan sifooyinka magnet oo aan xidhiidh shabakad. saamaynta ku daweynta Broad leeyihiin faashad magnetic kala duwan iyo applicators. Waxay xanuunka iyo joojiso habka bararka, iyo cuduro badan oo waxaa lagu daaweeyaa by saamaynta duurka magnetic ah oo ku saabsan goobaha firfircoon ee jirka aadanaha. Waxaa la og yahay in Cleopatra isticmaalo dahabka ah magnetic, si loo hagaajiyo socodka dhiigga iyo gabowga dib u dhac.

Qiimaha duurka magnetic for meeraha

duurka ku magnetic kaalin muhiim ah in nolosha caalamka. First of dhan, waxaa u adeegta sida ilaalinta ah ee deggan dhulka iyo Satellite ka saameynta ammaan ahayn maydadka runtan. Under saameynta ay duurka ku magnetic badalka ay dhabbihii. Cilmibaadhayaasha ayaa qirtay in qaar ka mid ah caalamka oo aan haysan core a birta, iyo halkan duurka ku magnetic, taas oo si weyn u yaraynaysaa tirada meerayaasha deggan suurto gal. Earthlings sidoo kale halis la tagay oo aan beerta ilaalinta. Laakiin in la yidhaahdo marka ay taasi dhici doona, iyo Geophysics laga qaadin. Daraasado ayaa muujiyey in ka badan 160 milyan oo sano ulaha magnetic - woqooyi iyo koonfur - kala duwan oo u dhexeeya qiyaastii boqol jeer. Munaasabadan ayaa waxaa la soo dhaafay sida qaaday 720,000 oo sano ka hor, iyo Earth la weeraray by qayb runtan. Mid ka mid ah aragtida sharxaya eynu ee dinosaurs ah, ayaa sheegay in kooxda ka dhisan, kuwaas oo baaba'aan kaliya sabab in.

duurka ku magnetic noqdo khafiif ah

Geophysics, falanqeeyo guryaha duurka magnetic, helay in ay jirto muuqan gelinba ammaan ahayn in aan la diiwaan ka hor. In South Atlantic lakabka field magnetic ah si tartiib tartiib ah khafiif. In ka badan 150 sano ee la soo dhaafay, duurka oo halkan ahaa nugul yihiin toban boqolkiiba. Qubarada ayaa sheegaya in shaqada pole dhici doono si deg deg ah oo ku filan, 100 sano gudahood tan iyo bilowgii inversion ah. Maxaa jiilka dhawri doonaa this ifafaale iyo sida ay u saamayn doonto dadka deggan dhulka, weli waa aan la aqoon, laakiin waxaa jira war sheegaya in wax isbedel ah oo ulihiina sida uu noqon doono dhaawici injineer koronto.

dabeylo magnetic iyo raadka ay ku leeyihiin dadka

Mararka qaarkood dhulka field magnetic waxaa jahwareeriyay - waa dabeylo magnetic, waa si toos ah ay ku xidhan tahay qorraxda. In muddo ah u kordhay dhaqdhaqaaqa qoraxda jirto daayo wayn ee tamarta, kaas oo ku kordhinaya formation of kicitaanka qoraxda. Xaaladdan oo kale, durdur Rafaa qayb eedeeyay socotaa in Earth ee xawaaraha sare - 500-1000 kilomitir labaad, abuuraya a beerta magnetic xoog leh. durdur Tani gaadho caalamka in dhawr maalmood. Isagoo ku sii jeeda laba field magnetic awood badan, oo beerta magnetic ugu danbeyn soo dhibtay oo dhulka. Nin caadaysteen in ay si caadi ah ay u duurka ku magnetic, iyo duufaan magnetic, caafimaadkiisa la beddelo.

Dadku shucuur magnetic kala duwan, saamaynta on duufaan magnetic aadanaha ku xiran tahay in ay xaaladdiisa caafimaad. Sii xumaanaya caafimaadka, koboca waa la dhimay, ku dhacaa dadka naafada ah, waxaa jira daciifnimo, madax xanuun, hurdo la'aanta, sii dartay howlgalka of habdhiska ah (tirada khaladaadka kordhay, tirada fashilaad iyo shilalka korodhka). In xidhiidh la leh muuqaalka kore ee dusha sare ee korontada ku alaabta on maalmood oo kale waxaa laga yaabaa in la jebiyey ee ay shaqadooda.

falcelinta ee xayawaanka duurka u magnetic

Waxaa caddeeyeen in shimbiraha yihiin si aad u wanaagsan dareemaan duurka ku magnetic of Earth iyo xitaa waxa ay u arkaan. Qubarada badankooda ayaa aaminsan in shimbiraha - uxuu u gaar ah sidan: ciidanka magnetic ka caawineysaa in la helo guryahooda inta lagu guda jiro duulimaad ku jiraan masaafo weyn.

beerta A magnetic waxaa loo isticmaalaa sida a qoolley badda Navigator. Xayawaanka la sare tusaale bisadaha magnetic horay uga jawaabaan isbedel ku xoogga magnetic field. dabeecadda xayawaanka aan caadi ahayn arkay ka hor duufaan iyo dhulgariir. Si loo go'aamiyo tsunami dhaw ama dhulgariirkii ka dhacay Japan ee quraaradda waaweyn ku jira dhulluxyo in ka hor dabiiciga ah kici dhaafsanaa oo ka walwalsan tahay, dareen perturbations xoogan oo duurka ku magnetic.

halkii epilogue ah

Saamaynta ay ku field magnetic on deggan oo dhulkeenna aan weli si buuxda u bartay, saynisyahano adduunka oo kaliya furay daaha of meeraha qarsoodiga Earth iyo isku dayaya in ay ka heli jawaabaha su'aalaha aad u muhiim ah. Laakiin horumarka aan weli taagan, iyo sayniska si degdeg ah horumarinta maalmahan, sidaasi darteed yaa og yahay, waxaa laga yaabaa in jiilka soo socda ogaan doonaa jawaabta ugu su'aalo ku saabsan oo la diriray maskaxda wanaagsan ee aadanaha.
