3) Hluav taws xob thiab hlau nplaum qhov tseem ceeb yog ob yam ntawm cov ib yam yam, vim kev hloov hluav taws xob teb tsim ib magnetic teb, thiab ib tug hloov magnetic teb tsim ib tug hluav taws xob teb. (Qhov no yog vim li cas physicists feem ntau hais txog "electromagnetism" lossis "electromagnetic" rog ua ke, tsis yog cais.)
Xav txog qhov no, qhov txawv ntawm hluav taws xob thiab hlau nplaum yog dab tsi?
Hluav taws xob muaj ntau dua ua rau hluav taws xob tam sim no thiab teb, thaum hlau nplaum tsom ntau dua rau cov teb thiab cov dej ntws ntawm qhov sib nqus. Hluav taws xob yog feem ntau piav raws li ib tug quab yuam uas tshwm sim thaum lub xub ntiag ntawm hluav taws xob nqi. Cov zog no tshwm sim vim kev hloov pauv hauv hluav taws xob nqi.
Ib sab saum toj no, koj puas tuaj yeem muaj hlau nplaum tsis muaj hluav taws xob? Tsis muaj koj tuaj yeem muaj magnetic teb tsis muaj ib hluav taws xob teb. Xav txog ib tug pas nrig nrog tus lej sib npaug ntawm qhov zoo thiab qhov tsis zoo (xws li lawv sib npaug sib npaug). Cia qhov zoo txav mus rau sab laug nrog ceev v thiab qhov tsis zoo mus rau sab xis nrog ceev v. Qhov no yuav ua rau lub magnetic teb tab sis tsis muaj hluav taws xob teb.
Puas yog hluav taws xob thiab hlau nplaum cuam tshuam?
Hluav taws xob thiab hlau nplaum nyob ze ntsig txog . Flowing electrons tsim ib qho chaw sib nqus, thiab spinning hlau nplaum vim a hluav taws xob tam sim no ntws. Electromagnetism yog kev sib cuam tshuam ntawm ob lub zog tseem ceeb no.
Dab tsi ua rau magnetism?
Magnetism yog ua rau los ntawm kev txav ntawm cov nqi hluav taws xob. Txhua yam khoom yog tsim los ntawm cov khoom me me hu ua atoms. Yog vim li cas cov ntaub ntawv xws li ntaub los yog ntawv thiaj li hais tias tsis muaj zog hlau nplaum. Nyob rau hauv cov khoom xws li hlau, cobalt, thiab npib tsib xee, feem ntau ntawm cov electrons spin nyob rau hauv tib txoj kev.

Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog tib yam hauv txhua qhov hluav taws xob hluav taws xob?
Electromagnetic hluav taws xob yog ib hom hluav taws xob uas feem ntau hu ua lub teeb. Feem ntau hais lus, peb hais tias lub teeb mus rau hauv nthwv dej, thiab tag nrho cov hluav taws xob hluav taws xob hluav taws xob mus rau tib qhov ceev uas yog li 3.0 * 108 meters ib ob los ntawm lub tshuab nqus tsev
Dab tsi yog qhov zoo ntawm kev siv lub tshuab hluav taws xob hloov hluav taws xob hauv atomic absorption?
Qhia qhov zoo thiab qhov tsis zoo ntawm lub cub tawg piv nrog kev siv cov nplaim taws hauv atomic absorption spectroscopy. Cov txiaj ntsig tseem ceeb yog ntau dua rhiab heev (concentration thiab tshwj xeeb tshaj yog loj). Lub ntsiab tsis zoo yog cov cuab yeej cuab tam ntau dua thiab cov nqi ntsuas
Kev sib raug zoo ntawm hluav taws xob thiab hluav taws xob teb yog dab tsi?
Electric teb yog txhais raws li lub zog hluav taws xob ib chav tsev nqi. Cov kev taw qhia ntawm lub teb yog coj mus rau qhov kev taw qhia ntawm lub zog nws yuav ua rau ib tug zoo kuaj nqi. Cov hluav taws xob hluav taws xob yog radially sab nraud los ntawm tus nqi zoo thiab radially mus rau qhov tsis zoo ntawm tus nqi
