Indlela Yokusebenza

1) Umphumela we-Magnetoeelectric

Ngokusho komthetho kaFaraday wokungeniswa kwe-electromay, ubukhulu bamandla we-electromotive elenziwe nge-coil kuncike ekushintsheni kwamazinga kazibuthe futhi usike umugqa wamandla kazibuthe (noma ukuguqulwa kwamandla kazibuthe kwenkaba kazibuthe lapho ikhoyili itholakala khona).

Umugqa oshukumisayo we-magnetoelectric

I-Linear Moving Magnetoelectric sensor iqukethe uzibuthe ongapheli, ikhoyili kanye nezindlu zezinzwa.

Lapho igobolondo liyathuthuka ngomzimba ovuthayo ukuze lilinganiswe futhi imvamisa yokudlidliza liphakeme kakhulu kunemvamisa yemvelo yenzwa, ngoba intwasahlobo ithambile futhi inqwaba yengxenye ehambayo idliwa (sekwephuze kakhulu) nomzimba ovuthayo. Ngalesi sikhathi, ijubane lokunyakaza okuhlobene phakathi kwezibuthe kanye nekhoyili isondele ngejubane lokudlidliza le-vibrator.

Uhlobo lokujikeleza

Insimbi ethambile, ikhoyili kanye nozibuthe ezingapheli kulungisiwe. Igiya lokulinganisa elenziwe ngezinto ezimagnazi zifakwa emzimbeni olinganisekayo wokujikeleza. Njalo lapho izinyo lijikelezwa, ukumelana kazibuthe kwe-magnetic paretuit okwakheke phakathi kwamagiya wokulinganisa kanye nezinguquko zensimbi ezithambile kanye, futhi i-magnetic flux nayo iyashintsha kanye. Imvamisa (inani lama-pulses) wamandla we-electromotive ashubile ku-coil alingana nomkhiqizo wenani lamazinyo kumagiya wokulinganisa kanye nesivinini sokujikeleza.

Umphumela wehholo

Lapho i-semiconductor noma i-foil yensimbi ibekwa emandleni kazibuthe, lapho ikhona manje (endaweni yokuqondisa yendiza ye-foil perpendicular kumandla kazibuthe) ukugeleza kwamandla, kukhiqizwa amandla kagesi okuqondiswa yi-perpendicular emakhazeni kazibuthe nakumanje. Le nto ibizwa nge-HALL FECH.

Into yehholo

Izinto ezisetshenziswayo ezisetshenziswayo zisetshenziswa i-germanium (GE), i-silicon (SI), i-Indium Antimonide (insb), i-Indium Arsenide (inas) nokunye. I-N-Type Germanium kulula ukuyikhiqiza futhi ine-coefficial enhle yehholo, ukusebenza kwezinga lokushisa kanye nokulingene. I-P-Type Silicon inokulinganiselwa okuhle kakhulu, futhi ukusebenza kwayo kwehholo kanye nokusebenza kwamazinga okushisa kuyafana naleyo ye-N-Type Germanium, kepha ukuhamba kwayo kwe-elektroni kuphansi futhi amandla ayo okulayisha ampofu, ngakho-ke kuvame ukusetshenziswa njengento eyodwa yehholo.
