Cov hlau nplaum yog tsim los ntawm kev nthuav tawm cov hlau ferromagnetic zoo li hlau thiab npib tsib xee rau cov hlau nplaum. Thaum cov hlau no kub rau qhov kub thiab txias, lawv dhau los ua cov hlau nplaum tas mus li. Nws kuj tseem tuaj yeem cuam tshuam lawv ib ntus los ntawm kev siv ntau txoj hauv kev koj tuaj yeem sim nyab xeeb hauv tsev. Kawm paub yuav ua daim ntawv hlau nplaum li cas, lub tshuab hluav taws xob, thiab cov hlau nplaum uas koj tuaj yeem siv ua lub ntsuas hluav taws xob.
Cov kauj ruam
Txoj Kev 1 ntawm 3: Ua Daim Ntawv Ntsia Hlau
Kauj Ruam 1. Sau cov khoom siv
Cov hlau nplaum ib ntus yooj yim tuaj yeem ua nrog cov hlau me me, xws li daim ntawv kaw, thiab lub tub yees hlau nplaum. Sau cov khoom no nrog rau cov hlau me me, xws li qhwv ntsej tom qab lossis ntsia hlau me me, uas koj tuaj yeem siv los ntsuas cov khoom sib nqus ntawm cov ntawv nplaum.
- Kev sim nrog cov ntawv sib txawv ntawm qhov sib txawv ntawm daim ntawv, thiab tsis muaj txheej txheem tiv thaiv cov ntawv qhwv.
- Sau cov khoom me me nyob hauv ntau qhov ntau thiab tsawg thiab hlau los saib seb cov twg yuav lo rau ntawm daim ntawv lo.
Kauj Ruam 2. Rub tus hlau nplaum tawm ntawm daim ntawv nplaum
Tsiv nws mus rau tib qho kev qhia, tsis yog rov qab thiab tawm mus. Siv tib lub suab nrawm koj yuav siv los ua qhov sib tw. Txuas ntxiv txhuam daim ntawv nrog daim hlau nplaum 50 zaug, sai li sai tau.
Kauj Ruam 3. Kov daim ntawv txiav tawm ntawm cov hlau me me
Puas yog cov hlau me me lo rau ntawm daim ntawv lo? Yog tias yog, koj tau ua tiav magnetized nws.
- Yog tias cov hlau yuav tsis lo rau ntawm daim ntawv qhwv, rub nws ntau dua 50 zaug thiab sim dua.
- Sim khaws lwm daim ntawv txiav thiab cov khoom loj los txiav txim siab tias cov hlau nplaum muaj zog npaum li cas.
- Xav txog kaw lub sijhawm ntev npaum li cas daim ntawv clip nyob qis qis tom qab qee tus lej rub. Kev sim nrog ntau hom hlau, zoo li tus pin lossis ntsia hlau, kom pom qhov twg ua rau muaj zog tshaj plaws, cov hlau nplaum ntev tshaj plaws.
Txoj Kev 2 ntawm 3: Ua Tus Hluav Taws Xob
Kauj Ruam 1. Sau cov khoom siv
Cov tshuab hluav taws xob tau tsim los ntawm kev siv hluav taws xob tam sim no los ntawm ib qho hlau los tsim kom muaj kev sib nqus. Qhov no tuaj yeem ua tiav ntawm qhov ntsuas me me siv cov khoom siv no, uas muaj nyob ntawm cov khw muag khoom kho vajtse:
- Tus ntsia hlau loj
- 3 ko taw ntawm cov tooj liab tooj liab xaim
- D-cell roj teeb
- Cov khoom sib nqus me me, zoo li daim ntawv los yog tus pin
- Cov hlua hlau
- Daim npog qhov ncauj
Kauj Ruam 2. Tshem qhov kawg ntawm xaim
Siv cov hlua hluav taws xob tshem tawm ob peb centimeters ntawm rwb thaiv tsev los ntawm qhov kawg ntawm cov xaim tooj liab. Qhov tsis muaj qhov kawg yuav muab qhwv ib ncig ntawm qhov kawg ntawm lub roj teeb.
Kauj Ruam 3. Muab cov ntsia hlau ntsia
pib txog 8 ntiv tes los ntawm qhov kawg ntawm cov hlau, qhwv cov ntsia hlau nruj. Txhua qhov qhwv yuav tsum tau kov kawg, tab sis tsis txhob sib tshooj lawv. Txuas ntxiv mus kom txog thaum cov ntsia hlau npog los ntawm lub taub hau mus rau qhov taub.
Nco ntsoov tias koj qhwv hauv tib txoj kev coj mus rau tus ntsia hlau. Txhawm rau tsim kom muaj qhov chaw sib nqus, cov hluav taws xob yuav tsum ntws hauv tib txoj kev
Kauj Ruam 4. Txuas lub roj teeb
Qhwv ib qho kawg ntawm cov xov hlau nthuav tawm ib puag ncig ntawm lub roj teeb zoo thiab lwm qhov kawg nyob ib puag ncig ntawm qhov tsis zoo ntawm lub roj teeb. Siv daim kab xev npog me me kom ruaj ntseg xaim rau ntawm ob sab.
- Tsis txhob txhawj txog qhov kawg ntawm xaim koj txuas rau qhov kawg ntawm lub roj teeb. Cov ntsia hlau yuav dhau los ua cov hlau nplaum ob txoj hauv kev; qhov sib txawv tsuas yog tias nws cov polarity yuav hloov. Ib sab ntawm cov hlau nplaum yog tus ncej sab qaum teb, thiab ib sab yog tus ncej qab teb. Kev thim rov qab cov xov hlau tseem yuav thim cov ncej.
- Thaum txuas lub roj teeb, cov xov hlau yuav kub dua thaum hluav taws xob pib dhau los ntawm lawv, yog li ceev faj tsis txhob hlawv koj tus kheej.
Kauj Ruam 5. Siv cov hlau nplaum
Muab tus ntsia hlau nyob ze ntawm daim ntawv los yog lwm daim hlau me me. Txij li tus ntsia hlau yog hlau nplaum, cov hlau yuav lo rau ntawm tus ntsia hlau. Sim nrog ntau qhov sib txawv thiab qhov hnyav kom pom tias koj lub zog muaj zog npaum li cas.
Txoj Kev 3 ntawm 3: Ua Compass Magnet
Kauj Ruam 1. Sau cov khoom siv
Ib txoj kab ntsuas hluav taws xob ua haujlwm los ntawm taw qhia rau sab qaum teb nrog rab koob magnetized uas haum nrog lub ntiaj teb qhov chaw sib nqus. Txhua yam hlau uas tuaj yeem ua hlau nplaum tuaj yeem hloov pauv mus rau hauv lub ntsuas hluav taws xob. Ib rab koob xaws los yog tus pin ncaj yog qhov kev xaiv zoo. Ntxiv rau rab koob, sau cov khoom siv no los ua koj lub koob:
- Ib tug magnetizer. Nrhiav cov hlau nplaum, tus ntsia hlau, lossis txawm tias ib daim plaub los nqus cov koob.
- Ib ntu hla ntawm cork. Hlais ib daim ntawv los ntawm cov cawv txiv hmab qub qub los muab lub hauv paus rau lub koob.
- Ib lub tais dej. Kev ncua qhov ntsuas hauv dej tso cai rau rab koob magnetized kom haum nrog lub ntiaj teb cov ncej sib nqus.
Kauj Ruam 2. Magnetize koob
Rub rab koob siv hlau nplaum, ntsia hlau, lossis daim plaub, uas tsim hluav taws xob me me. Rub rab koob rau tib qho kev qhia yam tsawg kawg 50 zaug kom nws nqus tau nws.
Kauj Ruam 3. Muab rab koob hla lub cork
Xaub nws hauv kab rov tav, kom lub koob txhaj rau ntawm ib sab cork thiab tawm mus rau lwm sab. Khaws thawb kom txog thaum lub hauv ntej thiab nraub qaum ntawm rab koob sib npaug los ntawm lub cork.
- Yog tias rab koob koj tab tom siv loj dhau los thawb lub cork, koj tuaj yeem yooj yim so nws saum lub cork.
- Yog tias koj tsis muaj nyiaj npib cork, siv lwm yam khoom hnyav uas ntab, xws li nplooj ntoo.
Kauj Ruam 4. Ntab cov hlau nplaum
Muab rab koob magnetized tso rau saum cov dej hauv lub tais. Saib raws li nws txav los sib dhos nws tus kheej los ntawm sab qaum teb thiab sab qab teb raws tus ncej. Yog tias nws tsis txav mus, tshem rab koob los ntawm lub cork, rub nws 75 zaug nrog lub tshuab nqus hlau, thiab sim dua.
Lub tswv yim
- Sim nrog qee yam me me kom nqa nrog cov hlau nplaum.
- Nco ntsoov khaws txhuam nws tib txoj kev.
- Qhov ntau zaus koj rub daim ntawv hla cov hlau nplaum ntau nws yuav tuav.
- Yog tias koj tso daim ntawv tso tseg, tej zaum nws yuav tsis ua haujlwm thiab koj yuav tau pib dua.
- Nco ntsoov tias koj tsuas yog rub hauv ib qho kev qhia.
- Thaum tsim lub tshuab hluav taws xob, cov xov hlau yuav tig kub. Ceev faj thaum ua haujlwm nrog lawv.
Lus ceeb toom
- Cov hlau nplaum tseem tuaj yeem lwv daim npav SIM hauv xov tooj, yog li ceev faj.
- Cov hlau nplaum tuaj yeem cuam tshuam TVs thiab Saib Xyuas (txawm hais tias daim ntawv xov hlau nplaum koj ua tej zaum yuav tsis)
- Koj yuav xav tau kev saib xyuas neeg laus yog tias tuav cov khoom no zoo li tshiab rau koj.
