Tsis zoo li cov hlau nplaum zoo tib yam, electromagnets kub… Yeej, electromagnets yog coils ntawm hlau qhwv ib ncig ntawm ib tug hlau core, uas nyob rau hauv lem txuas nrog lub roj teeb. Txawm hais tias lawv yooj yim los ua, lawv tuaj yeem muaj teeb meem nrog overheating yog tias muab hluav taws xob ntau dua li lawv cov xov hlau tuaj yeem tiv taus.

Koj tuaj yeem tiv thaiv lub tshuab hluav taws xob los ntawm kev kub dhau li cas?

Raws li tau hais, nws muaj peev xwm zam kom tsis txhob cua sov ntawm electromagnets. Txhawm rau ua qhov no, koj tuaj yeem muab txoj kab uas hla ntawm cov hlau nplaum, piv txwv li qhov kev ncua deb ntawm ib sab ntawm lub kauj mus rau lwm qhov, los ntawm 3.14. Tom qab ntawd, muab daim duab no los ntawm tus lej hloov ntawm lub kauj uas koj siv.

Yuav ua li cas electromagnet overheat?

Lawv yog qhov tseem ceeb tsuas yog cov coils ntawm cov hlau qhwv ib ncig ntawm cov tub ntxhais hlau thiab txuas mus rau lub roj teeb. Txawm hais tias lawv yooj yim ua hauv tsev, lawv tuaj yeem muaj teeb meem nrog overheating yog tias lawv tau txais ntau qhov hluav taws xob ntau dua li lawv cov xov hlau tuaj yeem ua tau. Hmoov zoo, nrog kev tsim qauv zoo, qhov no teeb meem tuaj yeem zam tau

Cov hlau nplaum ua kom sov?

tshav kub tuaj yeem tsim los ntawm cov hlau nplaumlos ntawm kev muab cov khoom sib nqus rau hauv qhov muaj zog oscillating magnetic teb uas ua rau cov hlau nplaum lub polarity hloov mus rau ntawm tus nqi siab txaus los tsim pom kev sib txhuam.

Yuav ua li cas thaum koj rhaub hluav taws xob?

Thaum rhuab saum 176 ° Fahrenheit (80 ° C), cov hlau nplaum yuav plam lawv cov khoom sib nqus sai. Lub hlau nplaum yuav dhau los ua kom tsis muaj zog tas liyog tias raug rau qhov kub no rau lub sijhawm ntev lossis ua kom sov ntawm qhov kub siab dua (Curie temperature).
