LEEM-6 Zipangizo Zoyesera Zoyesa Nyumba
Hall element yakhala ikugwiritsidwa ntchito kwambiri poyesa maginito chifukwa chochepa, yosavuta kugwiritsa ntchito, kulondola kwambiri, ndipo imatha kuyeza maginito a AC ndi DC. Ilinso ndi zida zina za malo, kusamutsidwa, liwiro, ngodya ndi muyeso wina wakuthupi ndi kuwongolera kosavuta. Woyesa zotsatira za Hall adapangidwa kuti athandize ophunzira kumvetsetsa zoyeserera za momwe Hall imagwirira ntchito, kuyeza kukhudzidwa kwa zinthu za mu Hall, ndikuphunzira momwe angagwiritsire ntchito zinthu za Hall kuyeza kupatsidwa mphamvu kwamaginito. Chida choyesera cha fd-hl-5 Hall effect chimatenga GaAs Hall element (sampuli) poyesa. Chigawo cha holo chimakhala ndi chidwi chazambiri, zazitali zazitali komanso koyefishienti yaying'ono, chifukwa chake zoyeserera ndizokhazikika komanso zodalirika.
Kufotokozera
Zipangizo zamaholo zakhala zikugwiritsidwa ntchito kwambiri poyesa maginito. Pamodzi ndi zida zina, zida za Hall zimagwiritsidwa ntchito pakuwongolera zokhazokha komanso kuyeza kwa malo, kusunthira, liwiro, ngodya, ndi zina zambiri. Zipangizozi zimapangidwa kuti zithandizire ophunzira kumvetsetsa tanthauzo la Hall effect, kuyeza kukhudzidwa kwa chinthu cha Hall, ndikuphunzira momwe angayesere maginito mwamphamvu ndi gawo la Hall.
Zoyesera
1. Chipangizo cha GaAs Hall chimakhala ndi chidwi chachikulu, kutalika kwake, komanso koyefishienti yaying'ono.
2. Kugwira ntchito kwakanthawi kochepa kwa gawo la Hall kumapereka chidziwitso chokhazikika komanso chodalirika choyesera.
3. Mawonekedwe owoneka bwino ndi kapangidwe kake ka mayeso oyeserera ndi gawo la Hall zokolola zabwino.
4. Chida cholimba chimaphatikizapo chitetezo.
Pogwiritsa ntchito chida ichi, zoyeserera zotsatirazi zitha kuchitidwa:
1. Pezani ubale pakati pamagetsi amtundu wa Hall ndi Hall pansi pamagetsi a DC.
2. Kuyeza kukhudzika kwa gawo la GaAs Hall.
3. Kuyeza maginito pamapindikira a pakachitsulo zitsulo zakuthupi ntchito GaAs Hall amafotokozera.
4. Yesani kugawa kwa a maginito motsatira njira yopingasa pogwiritsa ntchito chinthu cha Hall.
