Kushanda nzira

1) Magnetoelectric effect

Zvinoenderana nemutemo waFaraday weelectromagnetic induction, ukuru hwesimba remagetsi rakagadzirwa mucoil rinoenderana neshanduko yekuchinja kwemagineti inopfuura nepacoil apo N-turn coil inofamba mune magineti uye ichicheka mutsara wesimba remagineti. kana kuti magnetic flux shanduko yemagnetic field panowanikwa coil).

Linear inofamba magnetoelectric sensor

Iyo mutsara inofamba magnetoelectric sensor ine isingaperi magineti, coil uye sensor imba.

Kana goko richizunguzika nemuviri unodedera kuti kuyerwa uye kuwanda kwevibration kwakakwira zvakanyanya kupfuura kutenderera kwechisikigo kwesenso, nekuti chitubu chakapfava uye kuwanda kwechikamu chinofamba chakakura, yave kunonoka kune chikamu chinofamba. kudedera (kumira wakamira) nemuviri unobvunda.Panguva ino, nhanho yekufamba pakati pemagineti necoil iri padyo nekumhanya kwevibrator.

Rotary type

Simbi yakapfava, coil uye magineti echigarire zvakagadziriswa.Iyo yekuyera giya yakagadzirwa nemagineti conductive zvinhu inoiswa pane yakayerwa inotenderera muviri.Pese parinotenderedzwa zino, simba remagineti redunhu rinoumbwa pakati pegiya rekuyeresa uye simbi yakapfava inoshanduka kamwe chete, uye magineti inoshanduka zvakare kamwe chete.Iyo frequency (nhamba yemapulses) yeiyo induced electromotive force mucoil yakaenzana neyakagadzirwa nhamba yemazino pagiya rekuyeresa uye kumhanya kunotenderera.

Horo maitiro

Kana semiconductor kana simbi foil yakaiswa mune magineti, kana ikozvino (mune ndege inotungamira yefoil perpendicular kune magnetic field) inoyerera, simba re electromotive rinogadzirwa munzira inotarisana nemagnetic field uye ikozvino.Chiitiko ichi chinonzi Hall effect.

Horo element

Zvinowanzoshandiswa Hall zvinhu germanium (Ge), silicon (Si), indium antimonide (InSb), indium arsenide (InAs) zvichingodaro.N-mhando germanium iri nyore kugadzira uye ine yakanaka Hall coefficient, tembiricha kuita uye mutsara.P-type silicon ine mutsara wakanyanya, uye Horo yayo coefficient uye tembiricha kuita zvakafanana neyeN-mhando germanium, asi maerekitironi kufamba kwayo kwakadzikira uye kutakura kwayo kwakashata, saka haiwanzo shandiswa seImba imwe chete. element.
