4 Txoj Kev Yooj Yim Los Ntsuas Qhov Sib Nqus

Kev sib nqus, lub zog tsis pom uas rub qee yam khoom mus rau ib leeg, tau ua rau cov kws tshawb fawb thiab cov neeg xav paub xav paub xav paub xav paub ntau pua xyoo. Txij li cov compass uas coj cov neeg tshawb nrhiav hla dej hiav txwv loj mus rau cov thev naus laus zis hauv peb cov khoom siv niaj hnub, kev sib nqus ua lub luag haujlwm tseem ceeb hauv peb lub ntiaj teb. Kev kuaj xyuas kev sib nqus tsis tas yuav tsum muaj cov cuab yeej nyuaj; muaj cov txheej txheem yooj yim uas koj tuaj yeem siv los ntes qhov xwm txheej no. Nov yog plaub txoj hauv kev yooj yim los tshawb nrhiav cov khoom sib nqus ntawm cov khoom siv:

1. Kev Sib Nqus Sib Nqus:

Txoj kev yooj yim tshaj plaws los kuaj seb puas muaj hlau nplaum yog los ntawm kev soj ntsuam qhov sib nqus ntawm hlau nplaum. Siv ib lub hlau nplaum, zoo dua yog ib lubhlau nplaumlos yog lub hlau nplaum ko taw nees, thiab coj nws los ze rau cov khoom siv uas muaj lus nug. Yog tias cov khoom siv raug rub rau lub hlau nplaum thiab lo rau nws, ces nws muaj cov khoom sib nqus. Cov khoom siv sib nqus feem ntau suav nrog hlau, nickel, thiab cobalt. Txawm li cas los xij, tsis yog txhua lub hlau yog sib nqus, yog li nws tseem ceeb heev uas yuav tsum sim txhua yam khoom siv ib tus zuj zus.

2. Kev Ntsuas Lub Compass:

Lwm txoj kev yooj yim los nrhiav qhov magnetism yog siv lub compass. Cov koob compass yog cov magnets, nrog ib kawg feem ntau taw rau lub ntiaj teb lub magnetic north pole. Muab cov khoom ze ntawm lub compass thiab saib seb puas muaj kev hloov pauv hauv qhov kev taw qhia ntawm rab koob. Yog tias rab koob tig lossis txav thaum cov khoom raug coj los ze, nws qhia tias muaj magnetism nyob hauv cov khoom. Txoj kev no ua haujlwm zoo rau kev nrhiav txawm tias cov magnetic fields tsis muaj zog.

3. Cov Kab Sib Nqus:

Yuav kom pom tau qhovlub zog sib nqusNyob ib ncig ntawm ib yam khoom, koj tuaj yeem muab cov hlau nplaum rau ntawm ib daim ntawv uas muab tso rau saum cov khoom. Maj mam kov daim ntawv, thiab cov hlau nplaum yuav sib dhos raws cov kab sib nqus, muab ib daim duab qhia txog lub zog thiab lub zog ntawm lub zog sib nqus. Txoj kev no tso cai rau koj saib cov qauv ntawm lub zog sib nqus, pab koj nkag siab txog kev faib tawm ntawm cov hlau nplaum hauv cov khoom.

4. Kev Sib Nqus Uas Ua Rau Muaj Zog:

Muaj tej yam khoom siv uas yuav raug magnetized ib ntus thaum raug magnet. Yuav kom paub seb puas muaj magnetism, muab cov khoom ntawd tso ze rau ntawm magnet thiab saib seb nws puas raug magnetized. Tom qab ntawd koj tuaj yeem sim cov khoom uas raug magnetized los ntawm kev rub lwm yam khoom me me uas muaj magnetic los rau ntawm nws. Yog tias cov khoom ntawd tsuas muaj magnetic xwb thaum muaj magnet tab sis thaum tshem tawm, tej zaum yuav muaj magnetism.
