Xav paub yuav ua li cas thiaj ua rau koj tus kheej Electromagnet? Saib peb qhov Wonder Zone video saum toj no, lossis ua raws cov kauj ruam yooj yim no:
Txhawm rau ua qhov kev sim no hauv tsev, koj yuav xav tau:
1. Tus ntsia hlau loj, (kwv yees li peb ntiv tes ntev)
2. 3 ko taw ntawm cov xaim tooj liab tooj liab xaim
3. Lub roj teeb D cell tshiab
4. Qee daim ntawv txiav lossis lwm yam khoom siv hlau me me
5. Daim kab xev hluav taws xob.
Kauj Ruam 1: Ntsia Ntsia
1. Qhwv cov hlau kom nyob ib ncig ntawm tus ntsia hlau, tab sis sim tsis txhob sib tshooj nws tus kheej. Tso nws kom koj muaj tsawg kawg 6 - 7 ntiv tes lossis ntau dua ntawm cov xaim ntawm ob qho kawg. Ua kom ntseeg tau tias cov hlua tau nruj raws li qhov ua tau, ua kom nruj cov xaim qhwv, muaj zog dua cov hlau nplaum.
Kauj Ruam 2: Txuas Cov Hlau rau Lub Roj Teeb
2. Txhua tus hlau nplaum muaj tus ncej, zoo lossis tsis zoo. Cov ncej sib txawv tau nyiam sib. Tshem tawm qee cov yas txheej (yog txheej), thiab txuas ib qho ntawm cov xaim xaus rau sab tsis zoo ntawm lub roj teeb thiab ib qho ntawm cov xaim xaus rau sab zoo nrog daim kab xev hluav taws xob. Xyuas kom cov xaim txuas nrog lub roj teeb kom ruaj ntseg.
Kauj ruam 3: Ceev faj! Roj Teeb Tau Kub
3. TSEEM CEEB: Nws yog qhov zoo tshaj los kaw cov xov hlau mus rau lub roj teeb vim lawv yuav kub sai.
Kauj Ruam 4: Xeem Nws
4. Siv tus ntsia hlau koj tam sim no muaj hluav taws xob! Sim thiab khaws koj cov ntawv txiav thiab pom tias nws muaj zog npaum li cas. Electromagnets tsuas yog sib nqus thaum lub zog ntws. Cov hluav taws xob npaj cov qauv ntawm cov ntsia hlau zoo li lawv tuaj yeem nyiam qee yam hlau. Qhov no hu ua POLARIZATION. Tam sim no koj muaj lub tshuab hluav taws xob, koj puas tuaj yeem kuaj xyuas seb yam khoom twg koj tuaj yeem ua tau?
