LEEM-1 Helmholtz Coil Magnetic Field Apparatus
Kuyeza kwa ma coil maginito a Helmholtz ndichimodzi mwazinthu zofunikira kwambiri pakuyesa silabasi yoyeserera yamayunivesite athunthu ndi makoleji amisiri. Kuyesaku kungaphunzire ndikuzindikira njira yoyezera yamaginito ofooka, kutsimikizira kutsimikizika kwa mphamvu yamaginito, ndikufotokozera magawidwe amaginito malinga ndi zomwe amafunikira. Chida ichi chimagwiritsa ntchito 95A yolumikizira Hall sensor ngati chowunikira, imagwiritsa ntchito DC voltmeter kuyeza mphamvu yama sensa, ndikuwona maginito opangidwa ndi koyilo ya Helmholtz. Kulondola kwa muyeso kuli bwino kwambiri kuposa koyilo yozindikira. Chidacho ndi chodalirika, ndipo zoyeserera ndizolemera.
Ntchito yoyesera
1. Phunzirani njira yoyezera yamaginito ofooka;
2. Yesani maginito omwe amagawika pakatikati pa koloni ya Helmholtz.
3. Tsimikizani mfundo ya superposition maginito;
