Hwaro ano zvemagetsi okugadzira - the Chiitiko pamusoro remagetsi induction

Chiitiko pamusoro remagetsi induction mune zvemagetsi ouinjiniya chinhu nechimwe. Rave empirically yakawanikwa shure muna 1831 ne Chirungu yefizikisi Michael Faraday. Nepo zvazikamwa kuti pakati nemunhu uye magineti riri pedyo kudyidzana kunoitika. Zvaidavirwa kuti yakamisirwa mutariri dyidzana Via wemagetsi munda, uye kufamba kwavo (iyezvino) kunoratidzwa kuburikidza remagineti. Zvisinei, tariro kushandiswa hunobatsira ruzivo urwu Faraday kuti experimental zvabuda vaiva kujeka chaizvo. Kutaura zvazviri, musayendisiti uyo vawana Chiitiko pakati remagetsi induction, chakaratidza kutanga zvinokosha ano magetsi okugadzira.

Experience pachayo yakanga tsvarakadenga nyore: chidimbu zvechigarire magineti vakatanga kutama, uye akanga nominated nechepakati nzvimbo pakati majana ose coils. Mhedziso coils kwakanga kwakabatana kuti Switch mudziyo kuti kuyera zviduku tsika kuitika uye voltage.

Zvave akacherechedza kuti kana zvinofamba tsono magineti galvanometer dzikatsauka razero pfungwa. Zvino kutsaudzira waiva mukuru, ari magineti inodedera zvikuru kuzviita. Kana tikarangarira kuti nayo ine mbiri padanda mitsetse uye munda simba, zvinova pachena ukama pakati rinobva nekubudisa uye vakafurira iyezvino zvakasikwa.

Sezvo mamiriro haagoni nomuzvarirwo simuka mudunhu, vatiwo zviri pakuonekwa electromotive simba yakaitwa (EMF), izvo zvinozoita unokubvumira kugamuchira kutira. mutemo Faraday kunoita induction kunotibvumira kutaura kuti matambudziko kuti muitisi remagineti kusiyanisa panguva chinokonzera kuchinja yemagetsi munda uye, kana namahwindo redunhu ano.

Chiitiko pamusoro remagetsi induction akamutendera kuti echimurenga mhedziso anokonzera yemagetsi munda kungava kwete chete mhosva asiwo siyana remagineti. Gare gare akagadzira zvavo. Saka, mutemo Faraday kwakaita kuti remagetsi induction, inoti: pave remagineti EMF iri zvakananga novimba mwero kuchinja rinobva nekubudisa. Simba kuitika kunotangira namahwindo loop rinowanikwa maererano nomutemo Ohm vake.

Chiitiko pamusoro remagetsi induction maitire kwete chete nokuda kondakita asiwo muhombe conductive miviri. Saka, changing remagineti unobereka kondakita ukobvu (simbi yairema uye nezvimwewo.) Eddy dzenzvimbo. Vanovata kudziyisa pasingadiwi, saka dzakasiyana dzakashandiswa kuvabvisa (mu transformers ndiro laminations ose zvemagetsi simbi). Ona kuti mune dzimwe namano, Eddy dzenzvimbo anoshandiswa (Disc chizvidavirire counter).

Nokukurumidza, muna 1833, ari yefizikisi E. Lentz akatungamirira ushe, pahwaro iyo, vakafurira emf kunobereka kwazvino nhungamiro yakadaro kuti neutralize chikonzero chitarisiko chake. Somuenzaniso: kuchinja remagineti induces kuitika munyika kondakita. Rakagadzirirwa kuitira kuti yayo remagineti (ndiro chipo kunhivi akatakura ano-conductors) counteracted mudzi chikonzero.

Chiitiko pamusoro remagetsi induction akabvumira kuti vave zvemagetsi ouinjiniya ayo mamiriro. Zvakaoma kupa zvizere mazita midziyo inoshandisa. Somuenzaniso, basa emagetsi musimba miti kwakavakirwa chiitiko ichi. Zvisinei, zvisinei, chizvarwa vanokwanisa magadzirirwo kwave kuchiita kuchinja kubva Faraday, ndiye musimboti ndewokuti: mitsetse remagineti piringisha nomupirista kakawanda ano anoitisa windings, zvichiguma imwe electromotive simba uye, kana namahwindo loop magetsi iyezvino. Uyezve emagetsi uye Motors, induction Fani rinoshandiswa, semuenzaniso, mune transformers.
