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.
