Saib ib ncig, thiab koj yuav pom tias cov hlau nplaum nyob txhua qhov chaw, los ntawm lub xov tooj lossis lub computer uas koj siv los nyeem cov ntawv no mus rau lub qhov rooj ntawm koj lub wardrobe. Lawv kuj muaj nyob rau hauv hluav taws xob motors thiab generators thiab koob ntawm compasses. Cov hlau nplaum yog cov khoom siv uas siv lub zog sib nqus uas nyiam cov ncej thaum rov ua cov ncej tsis zoo li. Cov hlau nplaum yog tsim los ntawm ntau yam khoom sib txawv, tshwj xeeb tshaj yog cov hlau nplaum neodymium.

Cov hlau nplaum muaj qhov sib txawv; yog li ntawd, nws yog ib qho tsim nyog los tsim kom muaj lub zog ntawm cov hlau nplaum los txiav txim siab txog kev siv nws yog qhov zoo tshaj plaws. Ob qhov kev faib loj yog N50 hlau nplaum thiab N35 hlau nplaum. Hauv blog no, peb yuav tham txog lawv cov khoom thiab tsim kom muaj qhov twg ntawm ob yog qhov muaj zog tshaj plaws. Peb tseem yuav saib mus rau hauv kev ntsuas hlau nplaum, kuaj cov hlau nplaum lub zog, thiab yuav ua li cas xaiv cov hlau nplaum uas haum rau koj tus kheej.

Nkag siab Magnet Qib

Cov qib ntawm cov hlau nplaum yog qhov ntsuas ntawm nws lub zog. Cov hlau nplaum tau muab qhab nia ntawm qhov siab tshaj plaws uas lawv tuaj yeem tsim tau. Raws li koj tau pom nrog N50 hlau nplaum thiab N35 hlau nplaum, tsab ntawv sawv cev rau cov khoom siv los tsim cov hlau nplaum. Tsab ntawv 'N' yog siv rau cov hlau nplaum ua nrog neodymium. Lwm cov ntaub ntawv, xws lisamarium cobaltthiabalnico ua, kuj yog siv los tsim cov hlau nplaum.

Tus lej uas ua raws li tsab ntawv yog qhov ntsuas ntawm lub zog tiag tiag ntawm cov hlau nplaum. Txhawm rau txiav txim siab lub zog, kev ntsuas yog coj hauv Gauss, uas yog chav tsev uas qhia koj tias muaj zog txaus nyiam cov hlau nplaum muaj. Lwm chav tsev, Oersted, kuj yog ntsuas, uas qhia koj tias lub zog txaus nyiam ntawm cov hlau nplaum yog li cas.

Ob qho ntawm cov khoom no tseem ceeb rau cov hlau nplaum. Yog li ntawd, peb muab ob chav nyob no kom tau txais cov khoom siv hluav taws xob siab tshaj plaws, Mega Gauss Oersteds (MGO).
