LEEM-5 Hall Effect Experimental Apparatus

Kev sim
1. kawm txog lub hauv paus ntsiab lus ntawm Hall effect thiab kos duab qhov nkhaus ntawm Hall element.
2. kawm ntsuas lub zog magnetic induction B siv cov nyhuv Hall.
3. Ntsuas qhov faib ntawm lub zog sib nqus ntawm lub kauj hluav taws xob.
Cov kev tsis tseem ceeb
1. Qhov chaw tam sim no ntawm qhov excitation: 0 ~ 1.2A kho tau tas li, fineness <1mA, 3 thiab ib nrab LED cov zaub digital.
2. Qauv ua haujlwm tam sim no 0 ~ 5mA, kev ruaj khov <10-5, DC millivolt meter 0 ~ 20mV, kev daws teeb meem 10µV.
3. Hloov cov kev taw qhia tam sim no nrog kev hloov pauv zoo, zam qhov teeb meem ntawm kev puas tsuaj yooj yim ntawm relay thiab kev hloov pauv.
4. Tsim cov teb sib nqus nrog electromagnet, qhov loj me tam sim no thiab lub zog sib nqus tuaj yeem hloov kho.
