4 Txoj Kev Yooj Yim rau Kev Ntsuas Magnetism

Magnetism, lub zog tsis pom uas rub qee yam khoom ntawm ib leeg, tau nyiam cov kws tshawb fawb thiab xav paub ntau pua xyoo. Los ntawm compasses coj cov neeg tshawb nrhiav thoob plaws dej hiav txwv loj mus rau cov thev naus laus zis hauv peb cov khoom siv niaj hnub, hlau nplaum ua lub luag haujlwm tseem ceeb hauv peb lub ntiaj teb. Kev ntsuam xyuas cov hlau nplaum tsis tas yuav tsum muaj cov cuab yeej nyuaj; muaj cov txheej txheem yooj yim uas koj tuaj yeem siv los txheeb xyuas qhov tshwm sim no. Nov yog plaub txoj hauv kev yooj yim los tshawb txog cov khoom sib nqus ntawm cov khoom:

1. Sib nqus Attraction:

Txoj kev yooj yim tshaj plaws los ntsuas cov hlau nplaum yog los ntawm kev soj ntsuam cov hlau nplaum. Siv cov hlau nplaum, zoo dua abar hlau nplaumlos yog ib tug horseshoe hlau nplaum, thiab coj nws los ze rau cov khoom nyob rau hauv nqe lus nug. Yog hais tias cov khoom yog attracted rau cov hlau nplaum thiab lo rau nws, ces nws muaj cov khoom sib nqus. Cov khoom siv hlau nplaum muaj xws li hlau, npib tsib xee, thiab cobalt. Txawm li cas los xij, tsis yog tag nrho cov hlau yog hlau nplaum, yog li nws yog qhov tseem ceeb rau kev sim txhua yam khoom ntawm tus kheej.

2. Compass Test:

Lwm txoj hauv kev yooj yim los txheeb xyuas cov hlau nplaum yog siv lub compass. Compass koob yog lawv tus kheej cov hlau nplaum, nrog ib kawg feem ntau taw tes rau lub ntiaj teb cov hlau nplaum sab qaum teb. Muab cov khoom tso ze ntawm lub compass thiab saib xyuas txhua qhov kev hloov pauv ntawm rab koob txoj kev taw qhia. Yog tias rab koob deflects lossis txav thaum cov khoom raug coj los ze, nws qhia tias muaj cov hlau nplaum hauv cov khoom. Txoj kev no ua haujlwm zoo rau kev kuaj xyuas txawm tias tsis muaj zog magnetic teb.

3. Sib Nqus Field Kab:

Kom pom qhovmagnetic tebnyob ib ncig ntawm cov khoom, koj tuaj yeem nchuav hlau filings ntawm ib daim ntawv tso rau ntawm cov khoom. Maj mam coj mus rhaub cov ntawv, thiab cov ntaub ntawv hlau yuav kho lawv tus kheej raws cov kab sib nqus, muab cov duab sawv cev ntawm cov hlau nplaum cov duab thiab lub zog. Txoj kev no tso cai rau koj los soj ntsuam cov qauv sib nqus, pab koj nkag siab txog kev faib tawm ntawm cov hlau nplaum hauv cov khoom.

4. Induced Magnetism:

Qee cov ntaub ntawv tuaj yeem ua cov hlau nplaum ib ntus thaum coj mus rau hauv kev sib cuag nrog cov hlau nplaum. Txhawm rau ntsuas qhov induced magnetism, tso cov khoom nyob ze ntawm cov hlau nplaum thiab saib seb nws puas ua tau hlau nplaum. Tom qab ntawd koj tuaj yeem sim cov khoom siv hlau nplaum los ntawm kev nyiam lwm yam khoom me me ntawm nws. Yog tias cov khoom pov thawj cov khoom sib nqus tsuas yog nyob rau hauv lub xub ntiag ntawm cov hlau nplaum tab sis poob lawv thaum tshem tawm, nws yuav muaj kev cuam tshuam cov hlau nplaum.
