Ib electromagnet yog cov hlau nplaum uas khiav ntawm hluav taws xob. Tag nrho cov ntawm lawv me me magnetic teb ntxiv ua ke, tsim kom muaj zog magnetic teb. Raws li qhov tam sim no ntws nyob ib ncig ntawm lub hauv paus tseem ceeb nce, tus naj npawb ntawm cov atoms sib xyaw ua ke nce thiab qhov muaj zog ntawm cov hlau nplaum yuav ua tau.
Hais txog qhov no, daim ntawv yooj yim tshaj plaws ntawm lub tshuab hluav taws xob yog dab tsi?
Qhov tseeb, cov yooj yim electromagnet yog ib lub xaim uas yog coiled thiab muaj hluav taws xob khiav los ntawm nws. Cov hlau nplaum uas tsim los ntawm cov kauj hlau yog zoo li cov hlau nplaum ib txwm muaj. Yog tias peb muab hlau (lossis npib tsib xee, cobalt, thiab lwm yam)
Qhov thib ob, yuav ua li cas thaum lub tshuab hluav taws xob electromagnet tau qhib? Ib electromagnet yog tsim los ntawm kev hla qhov tam sim no los ntawm cov hlua hlau. Tsis zoo li cov hlau nplaum ib txwm muaj, electromagnets tuaj yeem yog tig rau thiab tawm. electromagnet . Ib electromagnet tuaj yeem yog tig rau los yog tawm.
| Nce qhov tam sim no | Tsis Yog |
|---|---|
| Ntxiv ntau tig ncig cov tub ntxhais | Tsis Yog |
| Tshem tawm cov tub ntxhais hlau ntawm electromagnet | Tsis Yog |
Ib yam li ib tus yuav nug, electromagnet yog dab tsi thiab nws siv li cas?
Hluav taws xob yog siv nyob rau hauv txhua yam khoom siv hluav taws xob, suav nrog hard disk drives, hais lus, lub cev muaj zog, thiab cov tshuab hluav taws xob, nrog rau hauv cov khoom seem kom khaws cov khoom hnyav. Lawv txawm siv hauv tshuab MRI, uas siv cov hlau nplaum los thaij duab ntawm koj sab hauv!
Yuav ua li cas tshwm sim thaum koj disconnect qhov hluav taws xob los ntawm ib tug electromagnet?
Lub magnetic teb ploj mus. Ntxiv cov coils ntxiv rau cov hlau los yog siv lub zog hluav taws xob qhov chaw.

Koj yuav tshem tus ntsia liaj qhov rooj uas tawg yooj yim li cas?
Tuav lub extractor me ntsis khov kho nrog T-kuav los yog xauv pliers. Muab lub extractor me ntsis rau hauv lub qhov pilot qhov nyob rau hauv lub puas screws. Siv ib tug rauj, coj mus rhaub lub extractor kom ruaj khov rau hauv lub qhov pilot. Siv downward siab rau lub extractor thaum tig nws counterclockwise kom tshem tawm cov ntsia hlau puas
Kuv tuaj yeem xeem tau yooj yim li cas?
Cov Kauj Ruam Muab sijhawm rau koj tus kheej txaus los kawm rau qhov ntsuas. Paub thaum twg qhov kev xeem yuav muab yog li nws tsis ua rau koj xav tsis thoob. Kawm ua ntej xeem. Txheeb xyuas cov kev xeem dhau los. Sib tov koj cov txuj ci kawm. Nrhiav cov ntsiab lus tseem ceeb tshaj plaws. Tau txais kev qhia. Ua ib daim ntawv txheeb xyuas. Ua kom tiav phau ntawv qhia kev kawm
Lub cav tsheb ua haujlwm yooj yim li cas?
Kev kub nyhiab ua rau qhov sib tov nthuav dav thiab thawb rov qab rau ntawm lub piston. Thaum lub txim hluav taws xob nthuav tawm qhov sib tov thiab thawb rau ntawm lub piston, lub piston thawb rov qab dua thiab xa qhov sib tov tawm ntawm lub tog raj kheej thiab mus rau hauv lub cav. Cov txheej txheem no tsim lub zog, uas lub cav siv los txhawb lub tsheb
Kuv yuav ua li cas thiaj ua rau kuv lub rooj zaum txhawb nqa tau yooj yim dua?
Yuav Ua Li Cas Kom Koj Tus Menyuam Yooj Yim Hauv Lub Rooj Zaum Booster Flatten nws. Yog tias tsim nyog, kho txhua yam. Rub nws tag nrho. Muab lub rooj zaum kom raug. Lub nraub qaum rov qab siv lub rooj zaum loj. Yog tias koj tus menyuam lub pob ntseg nyob saum lub rooj zaum ntawm lub tsheb, yuav tsum siv lub rooj txhawb nqa lub nraub qaum kom muaj kev tiv thaiv ntau dua rau lub caj dab. Lub kaum sab xis
Lub log yog lub tshuab yooj yim li cas?
Lub tshuab yooj yim hu ua lub log thiab qag yog hais txog kev sib dhos tsim los ntawm ob lub disks, lossis lub tog raj kheej, ntawm cov kab sib txawv mounted kom lawv tig ua ke nyob ib ncig ntawm tib axis.Cov pas nrig nyias uas yuav tsum tau tig yog hu ua lub qag thiab cov khoom dav dua. mus rau lub qag, uas peb siv zog yog hu ua lub log
