A solenoid yog cylindrical coil ntawm xaim uas nws txoj kab uas hla me me piv rau nws qhov ntev. Thaum hluav taws xob tam sim no ntws los ntawm cov xov hlau solenoid tsim ib qho chaw sib nqus zoo ib yam li cov hlau nplaum bar. Ib electromagnet yog ib tug solenoid mob nyob ib ncig ntawm lub hauv paus hlau core.

Ib sab ntawm qhov no, uas muaj zog dua solenoid lossis electromagnet?

CEEB TOOM: A solenoid tseem tsim tau ib qho chaw sib nqus tab sis tsis zoo li muaj zog as ib electromagnet ntawm tib qhov loj. Qhov tseeb, qhov chaw sib nqus nrog cov tub ntxhais hlau yog ntau dua 1, 000 zaug muaj zog (yog - ib txhiab zaus). Tsuas yog xav txog qhov tseem ceeb ntawm ib qho hluav taws xob muaj nws cov tub ntxhais nyiag thiab tam sim no muaj qhov khoob.

Tsis tas li ntawd, puas yog relay ib qho electromagnet? A relay yog ib hluav taws xob Hloov ua haujlwm los ntawm cov hluav taws xob me me uas tuaj yeem qhib lossis tawm hluav taws xob loj dua. Lub plawv ntawm a relay yog ib electromagnet (cov hlua hlau uas dhau los ua cov hlau nplaum ib ntus thaum hluav taws xob ntws los ntawm nws).

Ua qhov no hauv kev txiav txim siab, yuav ua li cas solenoid tuaj yeem siv ua hluav taws xob?

Ib electromagnet yog ib tug coil ntawm hlau nrog ib tug hluav taws xob tam sim no ntws los ntawm nws. Thaum cov hlau yog coiled nyob ib ncig ntawm lub tog raj kheej, peb hu qhov no a solenoid . Cov solenoid ua ib electromagnet thaum muaj dej ntws los ntawm nws. Tooj liab yog siv vim nws muaj hluav taws xob tsis zoo (saib cov khoom ua haujlwm).

Dab tsi yog qhov zoo tagnrho solenoid?

Nws yog paub zoo tias longitudinal magnetic teb sab nraum ib zoo tagnrho solenoid (piv txwv li, ib qho uas raug mob infinitely nruj thiab qhov ntev infinitely) yog xoom. Tom qab tag nrho, lub solenoid yog qhov kawg hauv qhov ntev thiab yog li nthuav mus rau infinity!
