Cov emf ua yog xwb xoom rau ib qho instant li cov hlau nplaum dhau los ntawm qhov chaw txaus ntawm coil . Qhov no yog vim qhov cuam tshuam ntawm N ncej ntawm ib kawg ntawm tus hlau nplaum ntawm qhov kawg ntawm qhov coil , yog raug tshem tawm los ntawm cov nyhuv ntawm S ncej ntawm lub hlau nplaum nyob rau lwm qhov kawg coil.
Xav txog qhov no, puas yog cov hlau nplaum hauv lub caij nplooj zeeg dawb nyob ze ntawm qhov chaw ntawm lub solenoid?
Raws li cov hlau nplaum tawm lub solenoid lub teb nyob rau hauv lub solenoid khiav nyob rau hauv tib txoj kev raws li hais tias ntawm hlau nplaum . Qhov no txhais tau tias cov poob bar hlau nplaum yuav xav tias muaj zog lwm yam tsis yog lub ntiajteb txawj nqus. Txawm li cas los xij, qhov hnyav ntawm qhov bar hlau nplaum Nws muaj ntau dua li cov hlau nplaum sib nqus, thiab peb kwv yees cov hlau nplaum txoj kev txav raws li kev poob siab.
Kuj Paub, yog vim li cas EMF yog induced nyob rau hauv lub kauj raws li cov hlau nplaum nkag mus rau nws? Txhua qhov kev hloov pauv hauv ib puag ncig sib nqus ntawm a coil ntawm cov hlau yuav ua rau muaj hluav taws xob ( emf ua ) ua " induced" nyob rau hauv lub coil . Cov ua emf hauv a coil yog sib npaug rau qhov tsis zoo ntawm tus nqi ntawm kev hloov ntawm magnetic flux lub sij hawm tus naj npawb ntawm lem nyob rau hauv lub coil . Nws suav nrog kev sib cuam tshuam ntawm tus nqi nrog magnetic teb.
Ib yam li ntawd, yuav ua li cas rau lub zog thaum lub hlau nplaum yog nyob ntawm qhov chaw ntawm lub kauj?
Thaum koj thawb ib hlau nplaum mus rau qhov chaw ntawm lub coil , ces rub nws tawm, galvanometer koob deflects nyob rau hauv ib qho kev taw qhia, ces lwm yam. Yog koj coj qaum teb kawg nkaus hlau nplaum mus rau coil , qhov induced emf tsim ib tug tam sim no uas txuam magnetic teb muaj nws sab qaum teb kawg taw tes rau lub hlau nplaum.
Yuav ua li cas tshwm sim thaum solenoid txav ceev ntawm lub bar hlau nplaum?
Tsiv tus bar hlau nplaum rau hauv tus solenoid induce ib e.m.f. hauv solenoid (raws li rau Faraday txoj cai), thiab vim hais tias lub Circuit Court raug kaw, ib tug tam sim no ntws thiab a Sib nqus teb yog induced.

Thaum lub ntiaj teb nyob nruab nrab ntawm lub hnub thiab lub hli lub hli theem yog?
Lub hli tag nrho tshwm sim thaum lub hli nyob rau sab nraud ntawm lub ntiaj teb los ntawm lub hnub, hu ua kev tawm tsam. Lunar eclipse tsuas yog tshwm sim thaum lub hli tag nrho. Lub hli waning gibbous tshwm sim thaum ntau tshaj ib nrab ntawm lub teeb ntawm lub hli tuaj yeem pom thiab cov duab txo qis ('wanes') loj los ntawm ib hnub mus rau lwm qhov
Yuav ua li cas koj pom qhov nruab nrab thiab nruab nrab ntawm daim duab peb sab?
Txhawm rau nrhiav qhov chaw nruab nrab ntawm daim duab peb sab, nws yog qhov yooj yim tshaj plaws los kos tag nrho peb qhov nruab nrab thiab nrhiav lawv qhov kev sib tshuam. Txhawm rau kos qhov nruab nrab ntawm daim duab peb sab, ua ntej nrhiav qhov nruab nrab ntawm ib sab ntawm daim duab peb sab. Kos ib kab ntu uas txuas qhov taw tes no mus rau qhov rov qab vertex
Qhov nruab nrab nruab nrab ntawm lub ntiaj teb yog dab tsi?

Qhov nruab nrab yog tus nqi nruab nrab hauv cov ntaub ntawv teev nyob rau hauv uas qhov tseem ceeb tau muab tso rau hauv kev txiav txim ntawm qhov loj
Koj ua li cas sib npaug redox cov tshuaj tiv thaiv hauv acidic thiab nruab nrab nruab nrab?
Acid Conditions Solution. Kauj Ruam 1: Sib cais ib nrab cov lus teb. Kauj Ruam 2: Ntsuas cov ntsiab lus uas tsis yog O thiab H. Kauj Ruam 3: Ntxiv H2O kom sib npaug ntawm cov pa. Kauj Ruam 4: Sib npaug hydrogen los ntawm kev ntxiv protons (H +). Kauj Ruam 5: Ntsuas tus nqi ntawm txhua qhov sib npaug nrog electrons.
