Ib electromagnet yog ib lub cuab yeej uas xa hluav taws xob los ntawm cov hlua hlau los tsim cov hlau nplaum. Hluav taws xob yog siv hauv ntau lab ntawm cov khoom siv thoob ntiaj teb, los ntawm hard disk drives thiab MRI tshuab, mus rau lub cav thiab lub tshuab hluav taws xob.

Cov lus nug tseem yog, kev siv hluav taws xob hluav taws xob yog dab tsi?

Electromagnets yog siv dav hauv cov khoom siv hluav taws xob thiab hluav taws xob, suav nrog:

  • Motors thiab generators.
  • Transformers.
  • Relays.
  • Tswb tswb thiab buzzers.
  • Lub suab nrov thiab lub mloog pob ntseg.
  • Actuators xws li li qub.
  • Sib nqus cov ntaub ntawv thiab cov khoom siv khaws cia: cov kab xev kaw, VCRs, hard disk.
  • MRI tshuab.

Ib qho ntxiv, cov tshuab hluav taws xob tau siv hauv tsev li cas? Cov Khoom Siv Hluav Taws Xob Hauv Tsev Lub solenoid valve sab hauv tshuab ntxhua khaub ncaws uas tig dej tawm lossis tso tawm yog ib yam electromagnet . Cov khib nyiab pov tseg, qhov cub microwave thiab induction cooktops txhua tus muaj electromagnets sab hauv lawv. Cov kab xev kaw, VCRs thiab DVD players kuj siv electromagnets los sau cov ntaub ntawv.

Kuj paub, lub tshuab hluav taws xob ua haujlwm li cas?

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.

Dab tsi yog piv txwv electromagnet?

Muaj ntau yam khoom siv hluav taws xob muaj electromagnets . Ib electromagnet yog ib txoj hlua hlau uas nyob ib ncig ntawm cov hlau lossis lwm yam khoom siv ferromagnetic. A: Txhua lub cuab yeej uas muaj lub tshuab hluav taws xob muaj electromagnets . Lwm yam piv txwv muaj xws li hairdryers, CD players, fais fab laum, hluav taws xob saws, thiab hluav taws xob mixers.
