Qhov sib txawv tseem ceeb ntawm hluav taws xob hluav taws xob thiab qhov chaw sib nqus yog qhov hluav taws xob piav qhia thaj chaw nyob ib puag ncig cov khoom siv hluav taws xob, qhov chaw sib nqus piav qhia thaj tsam ib puag ncig cov hlau nplaum uas cov ncej ntawm cov hlau nplaum qhia lub zog ntawm kev nyiam lossis kev tawm tsam.
Lub sij hawm hluav taws xob teb tau qhia los ntawm Michel Faraday thiab hais txog qhov chaw nyob ib puag ncig ntawm lub zog hluav taws xob uas tuaj yeem siv lub zog ntawm lwm qhov hluav taws xob hauv cheeb tsam. Sib nqus teb yog ib lo lus uas piav qhia txog kev sib nqus ntawm kev txav hluav taws xob, hluav taws xob tam sim no, thiab cov khoom sib nqus. Lub tswv yim no tau qhia los ntawm Hans Christian Oersted.
Ib qho hluav taws xob yog dab tsi?
Ib qho chaw hluav taws xob yog qhov chaw nyob ib puag ncig ntawm lub tshuab hluav taws xob uas tuaj yeem siv lub zog ntawm lwm cov khoom siv hluav taws xob hauv thaj teb. Peb tuaj yeem sau lo lus no ua E-field thiab. Cov khoom siv hluav taws xob hauv hluav taws xob tuaj yeem cuam tshuam los yog tshem tawm los ntawm lub hauv paus nqi tsev, nyob ntawm tus nqi hluav taws xob thiab lawv qhov loj.
Daim duab 01: Fais Field
Thaum xav txog qhov ntsuas atomic, lub teb hluav taws xob yog lub luag haujlwm rau lub zog txaus nyiam ntawm atomic nucleus thiab electrons. Lub zog txaus nyiam no yog cov kua nplaum uas tuav cov nucleus thiab cov hluav taws xob ua ke los ua tus qauv ntawm lub atom. Ntxiv mus, cov attraction zog no tseem ceeb nyob rau hauv chemical bond tsim. Chav ntsuas hluav taws xob yog volt per meter (V / m). Chav tsev no yog sib npaug zos rau chav tsev Newton ib coulomb (N/C) hauv SI unit system.
Magnetic Field yog dab tsi?
Magnetic field yog ib lo lus uas piav txog kev sib nqus ntawm kev txav hluav taws xob, hluav taws xob tam sim no, thiab cov khoom sib nqus. Nws yog vector teb. Feem ntau, kev txav mus los hauv qhov chaw sib nqus feem ntau ua rau muaj kev quab yuam uas nyob rau ntawm nws tus kheej tshaj tawm thiab mus rau qhov chaw sib nqus.
Daim duab 02: Kev Npaj Hlau Hmoov hauv Kev Sib Nqus
Thaum xav txog cov hlau nplaum ruaj khov, nws muaj nws qhov chaw sib nqus rub ntawm cov ntaub ntawv ferromagnetic, xws li. hlau, thiab nyiam los yog tawm tsam lwm cov hlau nplaum. Tsis tas li ntawd, ib qho chaw sib nqus zoo li sib txawv nrog qhov chaw ntawm thaj chaw, thiab nws tuaj yeem siv lub zog ntawm qee cov khoom tsis sib nqus los ntawm kev cuam tshuam cov kev txav ntawm sab nraud atomic electrons.
Feem ntau, ib qho chaw sib nqus nyob ib puag ncig cov hlau nplaum lossis cov khoom sib nqus. Cov chaw sib nqus no yog tsim los ntawm cov hluav taws xob tam sim no, xws li cov khoom siv hluav taws xob uas tshwm sim hauv electromagnets. Tsis tas li ntawd, lawv tuaj yeem tsim los ntawm cov chaw hluav taws xob uas sib txawv raws sijhawm. Ob lub zog thiab kev taw qhia ntawm ib qho chaw sib nqus sib txawv nrog qhov chaw. Peb tuaj yeem piav qhia nws ua lej siv lub luag haujlwm muab tus vector rau txhua qhov chaw ntawm qhov chaw (peb tuaj yeem hu nws ua vector field).
Qhov txawv ntawm Hluav Taws Xob thiab Sib Nqus Field yog dab tsi?
Lub sijhawm hluav taws xob tau qhia los ntawm Michel Faraday thaum lub tshav pob hlau nplaum tau qhia los ntawm Hans Christian Oersted. Qhov sib txawv tseem ceeb ntawm hluav taws xob thiab hluav taws xob sib nqus yog qhov hluav taws xob piav qhia thaj chaw nyob ib puag ncig cov khoom siv hluav taws xob, qhov chaw sib nqus piav qhia thaj chaw nyob ib puag ncig cov hlau nplaum uas cov ncej ntawm cov hlau nplaum qhia lub zog ntawm kev nyiam lossis kev tawm tsam. Tsis tas li ntawd, ib qho hluav taws xob tuaj yeem ua rau ob qho tib si txav thiab tsis txav cov khoom siv, qhov chaw sib nqus ua haujlwm tsuas yog ntawm cov khoom txav mus.
Cov infographic hauv qab no teev qhov sib txawv ntawm cov hluav taws xob thiab cov hlau nplaum hauv daim ntawv teev npe.
Summary – Electric Field vs Magnetic Field
Qhov sib txawv tseem ceeb ntawm hluav taws xob hluav taws xob thiab hluav taws xob sib nqus yog qhov hluav taws xob piav qhia thaj chaw nyob ib puag ncig cov khoom siv hluav taws xob, qhov chaw sib nqus piav qhia thaj chaw nyob ib puag ncig cov hlau nplaum uas cov ncej ntawm cov hlau nplaum qhia lub zog ntawm kev nyiam lossis kev tawm tsam.
