Indlela yokusebenza

1) Umphumela wamagnetic

Ngokomthetho kaFaraday wokungeniswa kwe-electromagnetic induction, ubukhulu bamandla e-electromotive akhangiwe akhiqizwa kukhoyili buncike ekushintsheni kwesilinganiso sikazibuthe esidlula kukhoyili lapho ikhoyili ye-N-turn ihamba endaweni kazibuthe futhi inqamula ulayini wamandla kazibuthe. noma uguquko oluguquguqukayo lukazibuthe lwensimu kazibuthe lapho ikhoyili ikhona).

Inzwa yamagnetoelectric ehamba ngomugqa

Inzwa yemagnetoelectric ehambayo ehambisanayo iqukethe uzibuthe ongapheli, ikhoyili kanye nendlu yezinzwa.

Lapho igobolondo lidlidliza nomzimba odlidlizayo ozolinganiswa futhi imvamisa yokudlidliza iphakeme kakhulu kunemvamisa yemvelo yenzwa, ngenxa yokuthi intwasahlobo ithambile futhi isisindo sengxenye enyakazayo sikhulu ngokuqhathaniswa, sekwephuzile kakhulu ngengxenye enyakazayo. ukudlidliza (ukuma unganyakazi) ngomzimba odlidlizayo.Ngalesi sikhathi, isivinini sokunyakaza esihlobene phakathi kukazibuthe nekhoyili siseduze nesivinini sokudlidliza sesidlidlizi.

Uhlobo lwe-Rotary

Insimbi ethambile, ikhoyili kanye nezibuthe ezihlala njalo zilungisiwe.Igiya lokulinganisa elenziwe nge-magnetic conductive material lifakwa emzimbeni ojikelezayo okaliwe.Ngaso sonke isikhathi lapho izinyo lizungeziswa, ukumelana kuzibuthe kwesekethe kazibuthe yakheka phakathi kwegiya lokulinganisa kanye nensimbi ethambile kushintsha kanye, futhi ukugeleza kazibuthe nakho kushintsha kanye.I-frequency (inombolo yama-pulses) yamandla e-electromotive eyenzelwe ikhoyili ilingana nomkhiqizo wenombolo yamazinyo egiyeni lokulinganisa kanye nesivinini esijikelezayo.

Umphumela wehholo

Lapho i-semiconductor noma i-foil yensimbi ibekwe endaweni kazibuthe, lapho i-current (inkomba yendiza ye-foil perpendicular to the magnetic field) igeleza, amandla e-electromotive akhiqizwa endaweni eqondile yenkundla kazibuthe namanje.Lesi simo sibizwa nge-Hall effect.

Ingxenye yehholo

Izinto ezisetshenziswa kakhulu zeHholo i-germanium (Ge), i-silicon (Si), i-indium antimonide (InSb), i-indium arsenide (InAs) njalonjalo.I-germanium yohlobo lwe-N kulula ukuyikhiqiza futhi ine-coefficient ye-Hall enhle, ukusebenza kahle kwezinga lokushisa kanye nomugqa.I-silicon yohlobo lwe-P inomugqa omuhle kakhulu, futhi ukusebenza kweHholo layo kanye nokusebenza kwezinga lokushisa kuyefana naleyo ye-N-type germanium, kodwa ukuhamba kwayo kwe-electron kuphansi futhi umthamo wayo wokulayisha uphansi, ngakho ngokuvamile awusetshenziswa njengeHholo elilodwa. isici.
