Lub tshuab hluav taws xob ua haujlwm li cas: Magnetism

Hluav taws xoblub cev muaj zogyog ib feem tseem ceeb ntawm suav tsis txheeb cov tshuab thiab khoom siv uas peb siv hauv peb lub neej txhua hnub.Los ntawm kev siv lub tshuab hluav taws xob rau kev tsav tsheb thiab txawm tias nyob rau hauv cov khoom siv hauv tsev niaj hnub, lub tshuab hluav taws xob yog qhov tseem ceeb ntawm cov cuab yeej siv niaj hnub no.Nyob rau hauv lub plawv ntawm yuav ua li cas hluav taws xob motors ua hauj lwm yog lub fascinating thiab tseem ceeb quab yuam ntawm hlau nplaum.

Magnetsua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov tshuab hluav taws xob.Cov khoom muaj zog no tsim ib qho chaw sib nqus nyob ib puag ncig lawv, thiab nws yog qhov chaw sib nqus no uas cuam tshuam nrog cov hluav taws xob tam sim no los tsim cov lus tsa suab.Tshwj xeeb, bar hlau nplaum thiab electromagnets yog qhov tseem ceeb rau kev ua haujlwm ntawm lub tshuab hluav taws xob.

A bar hlau nplaumtsuas yog ib qho ncaj nraim ntawm cov khoom sib nqus nrog rau sab qaum teb thiab sab qab teb ncej.Thaum ib lub hlau nplaum nyob ze rau ntawm qhov hluav taws xob, nws tsim ib qho chaw sib nqus nyob ib puag ncig nws.Qhov chaw sib nqus no cuam tshuam nrog cov neeg nqa khoom tam sim no hauv lub cev muaj zog, ua rau lawv muaj kev quab yuam thiab txav mus raws li.

Lub caij no, electromagnets yog tsim los ntawm kev qhwv ib lub kauj nyob ib ncig ntawm cov khoom siv tseem ceeb, xws li hlau, thiab tom qab ntawd hla cov hluav taws xob los ntawm lub kauj.Qhov no tsim ib qho chaw sib nqus nyob ib ncig ntawm lub kauj, thiab cov khoom siv tseem ceeb ua rau lub zog ntawm cov hlau nplaum.Electromagnets yog dav siv nyob rau hauv hluav taws xob motors vim hais tias lawv muab tau yooj yim dua thiab tswj ntawm magnetic teb.

Kev sib cuam tshuam ntawm magnetic teb thiab cov tam sim no yog qhov tseem ceeb ntawm kev siv hluav taws xob ua haujlwm li cas.Cias muab, thaum hluav taws xob tam sim no dhau los ntawm ib tug neeg xyuas pib nyob rau hauv lub xub ntiag ntawm ib tug magnetic teb, ib tug quab yuam yog exerted rau tus neeg xyuas pib, ua rau nws txav mus.Cov lus tsa suab no ua rau cov neeg kho tshuab ua haujlwm ntawm lub tshuab hluav taws xob, txawm tias nws yog kiv cua, txav lub tsheb, lossis khiav cov cuab yeej txiav.

Kev nkag siab txog cov hlau nplaum yog qhov tseem ceeb rau kev nkag siab tias lub tshuab hluav taws xob ua haujlwm li cas.Magnetism yog lub zog uas tsim cov magnetic teb uas tsav lub zog ntawm lub cev muaj zog.Qhov kev quab yuam no kuj yog vim li cas cov hlau nplaum thiab cov hlau nplaum yog qhov tseem ceeb ntawm kev tsim hluav taws xob tsim hluav taws xob.

Hauv cov ntsiab lus, txoj hauv kev ua haujlwm ntawm lub tshuab hluav taws xob yog ua raws li cov hlau nplaum.Txawm hais tias los ntawm kev siv cov hlau nplaum los yog cov hlau nplaum electromagnets, lub cim ntawm ib qho chaw sib nqus thiab nws cov kev cuam tshuam nrog hluav taws xob tam sim no tso cai rau lub tshuab hluav taws xob los ua nws txoj haujlwm yooj yim.Raws li kev siv tshuab txuas ntxiv mus, kev nkag siab thiab kev siv cov hlau nplaum hauv cov tshuab hluav taws xob yuav txuas ntxiv mus ua lub luag haujlwm tseem ceeb hauv kev tsim lub ntiaj teb nyob ib puag ncig peb.
