Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm cov hlau nplaum tas mus li thiab cov hlau nplaum hluav taws xob?

Dab tsi yog qhov zoo sib xws thiab qhov sib txawv ntawm cov hlau nplaum ruaj khov thiab electromagnets?

Qee zaum, cov neeg siv khoom yuav tham nrog peb lub tuam txhab los yuav cov khoom siv hluav taws xob. Nyob rau hauv lawv lub tswv yim, hlau nplaum thiab electromagnets yuav zoo sib xws. Yog tias koj tuaj yeem ua cov hlau nplaum, koj tuaj yeem ua ib qho electromagnet. Qhov tseeb, nws tsis yog. Hnub no kuv yuav qhia koj txog qhov zoo sib xws thiab qhov sib txawv ntawm electromagnets thiab hlau nplaum.

Electromagnet - Ib lub zog solenoid nrog cov tub ntxhais hlau hauv cov hlau nplaum. Thaum cov tub ntxhais hlau ntxig rau hauv lub zog solenoid, cov tub ntxhais hlau yog magnetized los ntawm cov hlau nplaum ntawm lub zog solenoid. Cov hlau nplaum hlau tseem tuaj yeem ua cov hlau nplaum. Nws yog cov txheej txheem ntawm kev hloov hluav taws xob rau hauv lub zog sib nqus, thiab tom qab ntawd los ntawm lub zog sib nqus mus rau hauv lub zog kinetic (hluav taws xob zog → sib nqus zog → kinetic zog). Yog li ntawd, qhov voltage, tam sim no, tsis kam, thiab lub zog muaj feem xyuam rau cov txheej txheem tsim hluav taws xob hluav taws xob. Nyob rau hauv tus txheej txheem ntawm magnetic zog tsim, nws muaj magnetic induction, magnetic flux thiab thiaj li nyob.

Cov hlau nplaum tas mus li - nws tuaj yeem yog cov khoom siv ntuj tsim lossis tsim khoom tsim tawm (cov hlau nplaum muaj zog tshaj plaws yog neodymium hlau boron hlau nplaum). Nws muaj qhov dav hysteresis voj, siab coercive quab yuam, thiab siab remanence, thiab muaj peev xwm tswj tau ib qhov chaw sib nqus tas li ib zaug magnetized s khoom. Kuj tseem hu ua cov khoom siv hlau nplaum ruaj khov, cov khoom siv hlau nplaum nyuaj. Nyob rau hauv daim ntawv thov, cov hlau nplaum ruaj khov ua haujlwm nyob rau hauv lub thib ob quadrant demagnetization ib feem ntawm cov hlau nplaum rov qab kab tom qab sib sib zog nqus saturation thiab magnetization. Cov hlau nplaum tas mus li yuav tsum muaj lub zog siab Hc, remanence Br thiab cov khoom siv hluav taws xob siab tshaj plaws (BH) m raws li qhov ua tau kom ntseeg tau qhov siab tshaj plaws sib nqus zog cia thiab ruaj khov magnetic zog.

Dab tsi yog qhov zoo sib xws ntawm electromagnet thiab hlau nplaum?
Ob qho tib si muaj qhov sib xws yog tias lawv ob leeg muaj qhov sib nqus thiab sib nqus.

Dab tsi yog qhov txawv ntawm electromagnets thiab hlau nplaum?
1. Cov hlau nplaum yuav tsum tau siv hluav taws xob los ua cov hlau nplaum, thiab cov hlau nplaum feem ntau tshwm sim tom qab tau hlau nplaum yam tsis muaj hluav taws xob.
2. Lub zog sib nqus ntawm lub tshuab hluav taws xob tuaj yeem hloov pauv, uas cuam tshuam nrog cov lej hloov ntawm lub kauj thiab qhov kev siv tam sim no, tab sis lub zog sib nqus ntawm cov hlau nplaum tsis tuaj yeem hloov pauv.
3. Cov ncej hlau nplaum (S / N) ntawm cov hlau nplaum tuaj yeem hloov tau, uas yog txiav txim siab los ntawm qhov zoo thiab qhov tsis zoo ntawm cov hluav taws xob thiab cov kev taw qhia winding ntawm lub kauj, thaum lub hlau nplaum ntawm cov hlau nplaum ruaj khov.
4. Cov khoom siv hluav taws xob feem ntau yog siv rau hauv cov chaw ua haujlwm loj los ua kom cov khoom ua tiav loj rau cov haujlwm, thaum cov hlau nplaum feem ntau yog siv rau hauv ntau yam khoom siv hauv tsev, khoom siv hluav taws xob, lub cev muaj zog, hais lus, thiab cov tsev ntse.
5. Cov hlau nplaum muaj cov coils, tab sis cov hlau nplaum tsis muaj coils.
6. Kev siv cov khoom siv hluav taws xob muaj teeb meem. Piv txwv li, lub tshuab hluav taws xob tiv thaiv tsis ua haujlwm yog nruab los ua kom muaj kev nyab xeeb. Kev siv cov hlau nplaum yog qhov yooj yim thiab yooj yim.

Los ntawm cov lus qhia saum toj no rau qhov zoo sib xws thiab qhov sib txawv ntawm electromagnets thiab hlau nplaum, kuv ntseeg tias koj muaj koj tus kheej xaiv.
