Puas yog lub teeb liab ntsuas los ntawm induction xeem cwj mem yog magnetic teb los yog hluav taws xob?
Induction xeem cwj mem, feem ntau sim hloov tam sim no. Lub alternating hluav taws xob teb thiab alternating magnetic teb nyob ib ncig ntawm lub alternating tam sim no yog perpendicular rau ib leeg. Nws yog qhov tseeb ntawm electromagnetic teb. Nco ntsoov thiab txeeb qhov kev sim Oster:
Oersted qhov kev sim qhia tau hais tias muaj ib qho chaw sib nqus nyob ib ncig ntawm lub zog hlau thiab nyob ib ncig ntawm cov hlau nplaum ruaj khov. Oersted qhov kev sim qhia qhov tseem ceeb heev - muaj qhov sib nqus teb nyob ib puag ncig tam sim no, thiab tam sim no yog tsim los ntawm kev taw qhia ntawm lub zog hluav taws xob, yog li cov hlau nplaum nyob ib ncig ntawm lub zog hlau yog qhov tseem ceeb tsim los ntawm kev txav hluav taws xob. Qhov tshwm sim no tau tshawb pom thawj zaug los ntawm Danish physicist Oster thaum Lub Xya Hli 1820.
Thaum lub voj voog nyob rau hauv ib txwm muaj, Q1 tsim cov xau tam sim no vim lub rooj vag ntab, tsis muaj tam sim no ntws mus rau hauv lub hauv paus ntawm Q2, thiab Q3 yog nyob rau hauv lub xeev extinguished. Thaum lub phaj induction nyob ze rau AC fais fab mov ntawm 220V los yog siab dua, vim hais tias lub hwj chim mov yuav tsim ib tug alternating hluav taws xob teb nyob ib ncig ntawm nws, lub induction phaj yuav induce tus coj alternating voltage thiab ntxiv rau lub rooj vag ntawm Q1. Thaum qhov induced voltage ntawm lub phaj induction yog qhov tsis zoo, Q1 Txiav tawm, V voltage ntxiv rau lub hauv paus ntawm Q2 txog R1 thiab Q4, Q2 yog qhib, thiab Q3 emits lub teeb. hluav taws xob Circuit Court, uas ua rau tam sim no). Nws dhau los ua unidirectional tam sim no los ntawm diode, thiab tom qab ntawd nthuav dav los ntawm triode, thiab thaum kawg mus txog lub teeb-emitting diode.
Kuv soj ntsuam, induction xeem cwj mem, induced teeb liab yog: alternating electromagnetic teb nyob ib ncig ntawm lub alternating tam sim no (tsim induced electromotive quab yuam, input direct tam sim no
