Mibvunzo yemuenzaniso uye mafomura emutemo weAmpere weEMF induced transformer

Mutemo weAmpere

1. Sekureva kwaH.C. Oersted, magetsi anogadzira simba remagineti. Vachigadzira dzidziso iyi, coil inotakura magetsi anogadzirawo simba remagineti. Coil iyo, painotakura magetsi, inogadzira simba remagineti rakafanana nerinogadzirwa nemagneti yebar...

A. toroid
B. solenoid
C. waya yakakoshwa
D. tambo yerectangular

Kukurukurirana

Magineti ine matanda maviri: danda rekuchamhembe nedanda rekuchamhembe. Simba remagineti rinogadzirwa nemagneti repamusoro rinomiririrwa nemitsetse yemagetsi, inotangira padanda rekuchamhembe ichipinda padanda rekuchamhembe.
Simba remagineti rinogadzirwa nemagneti yebar rakafanana nesimba remagineti rinogadzirwa nesolenoid, sezviri pamufananidzo uri padivi.
Solenoid isimbi refu yewaya ine matendererero akawanda. Mufananidzo uri pazasi unoratidza muenzaniso wekugadzira magineti nekuputira simbi yewaya yakaitenderedza. Kwakananga matanda emagineti kunogona kuzivikanwa uchishandisa mutemo wekurudyi.
Tambanudza ruoko rwako rwerudyi, uchiruisa panzvimbo yekuti chanza chitarise kumeso kwako. Tambanudza chigunwe chako wobva wakotamisa mimwe minwe mina kumberi kumeso kwako. Kuenda kwezvigunwe zvina kunoenderana nekwakatenderera kwemagetsi ari mukoiri, ukuwo chigunwe chakanongedzera kumucheto wekuchamhembe kwesimba remagineti. Chigunwe chakanongedzera kumucheto weN, saka N inomiririra mucheto wekuchamhembe wegineti uye M inomiririra danda rekumaodzanyemba regineti.

Toroid

2. Simba remagineti rinogadzirwa netoroid rinotakura magetsi rine gwara….

A. yakatarisana nendege ye toroid
B. denderedzwa
C. kudzokera shure nekudzoka
D. zvinoenderana nenguva

Kukurukurirana
Toroid idenderedzwa remagetsi saka uchishandisa mutemo weruoko rwerudyi, simba remagineti rinogadzirwa netoroid rine gwara rakatenderera.

EMF inokonzereswa

3. Kana magineti ikaiswa mu coil, simba remagetsi rinokonzereswa richaitika pakati pemagumo e coil. Chiitiko ichi chinokonzerwa ne...
A. Pane shanduko munzira yesimba remagineti inocheka coil.
B. pane shanduko mumatanda emagineti anocheka coil
C. Pane shanduko muhuwandu hwemitsara yemagineti yesimba inocheka coil.
D. pane kudzikira kwenhamba yemitsetse yemagineti yesimba inocheka coil

Simba remagetsi rinokonzereswa rinogadzirwa nesimba remagineti rinoshanduka. Hukuru hweEMF inokonzereswa hahubvi pahuwandu hwekuchinja kwesimba remagineti asi pahuwandu hwekuchinja kwesimba remagineti. Magnetic flux inhamba yemitsara yesimba remagineti inopfuura nepa coil. Fomura yemasvomhu yesimba remagineti ndiΦ_B = BA cos θ. Kana mitsetse yemagnetic field yakatarisana nenzvimbo yepamusoro ye coil, ipapo kona inoumbwa pakati pemitsetse yemagnetic field nemutsetse wakajairika i0_o, apo cosine iri 0_o = 1. Kana mitsetse yemagnetic field yakaenzana nenzvimbo yepamusoro ye coil saka kona yakagadzirwa i90^o, apo cosine iri 90^o = 0. Saka magnetic flux ine kukosha kushoma kana mitsetse yemagnetic field yakaenzana nenzvimbo yepamusoro yecoil uye kukosha kwakanyanya kana mitsetse yemagnetic field yakatarisana nenzvimbo yepamusoro yecoil.
Hukuru hwe emf inokonzereswa hunoverengerwa uchishandisa mutemo waFaraday we induction formula:

Chiratidzo chekuramba chinoratidza kuti simba remagetsi rinokonzerwa nemagetsi rinoburitsa magetsi akasiyana nekwakabva shanduko yeflux. Chirevo ichi chinonzi mutemo waLenz.
Mhinduro chaiyo ndiC.

4. EMF inokonzerwa inoitika mu coil inowedzera mumutsara nekufamba kwenguva. Kana nzvimbo yepamusoro ye coil ikaramba yakafanana uye simba remagineti rakamira rakatarisa pamusoro pe coil, saka girafu yesimba remagineti inogona kuwanikwa pamamiriro aya ndeye….

Hukuru hwe emf inokonzereswa hunoverengerwa uchishandisa mutemo waFaraday we induction formula:

Kana simba remagetsi rakamira rakanamira pamusoro pe coil saka:

Information :

Kana simba remagineti rakamira pamusoro pe coil, fomura ye magnetic flux ndeiyi:

B = simba remagineti, A = nzvimbo yepamusoro pe coil.
Nzvimbo yepamusoro pe coil ine kukosha kwakatarwa uye simba remagineti rakamira pamusoro pe coil saka rine kukosha kwakatarwa.
Saka zvichibva pafomura iri pamusoro apa, zvinogona kugumiswa kuti chinopesvedzera kukosha kwe induced emf itsvedzero yekuchinja kweflux, kana rate yekuchinja kweflux yakakura saka induced emf yakakura.

Transformer mudziyo wekushandura voltage ye alternating current (AC). Kune mhando mbiri dze transformers: step-up transformers uye step-down transformers. Step-up transformers inowedzera voltage, nepo step-down transformers ichideredza voltage.
Step up transformer inoshanda kuwedzera voltage kuitira kuti hunhu hwayo huve:
1. Voltage yekutanga idiki, voltage yechipiri yakakura
2. Magetsi ekutanga akakura, echipiri akadiki
3. Huwandu hwema "primary turns" hushoma, huwandu hwema "second turns" hwakawanda

Hunhu hwe transformer inodzika pasi hunoshanda kuderedza voltage kuitira kuti hunhu hwacho huve:
1. Voltage yekutanga yakakura, voltage yechipiri idiki
2. Magetsi ekutanga madiki, echipiri madiki
2. Huwandu hwema "primary turns" hwakakura, huwandu hwema "second turns" hwakaderera.

Simba remagetsi isimba remagetsi rinoshandiswa panguva yakatarwa. Simba rinochengetwa, saka simba rinochengetwawo. Naizvozvo, simba remagetsi riri mu coil yekutanga rakaenzana nesimba remagetsi riri mu coil yechipiri, uye ndizvo zvakaitawo simba remagetsi.
Fomura yesimba remagetsi:
P = VI
Tsananguro: P = simba remagetsi, V = voltage yemagetsi, I = magetsi emagetsi
Simba risingaperi, zvichibva pafomura iyi, zvinogumiswa kuti kana voltage yemagetsi yakakura, saka magetsi emagetsi madiki zvekuti chigadzirwa chemagetsi emagetsi nemagetsi ane simba zvine kukosha kusingagumi.
