LEEM-1 Helmholtz Coil Magnetic Field Apparatus Kiʻi ʻia

LEEM-1 Helmholtz Coil Mea Mana Mākēneki

ʻO ka wehewehe pōkole:

Loaʻa iā ia nā hiʻohiʻona o ka hoʻololi pinepine o ka hōʻailona excitation a me ka ikaika o ka hoʻopuka hoʻololi.
ʻO Helmholtz coil magnetic field ana kekahi o nā hoʻokolohua koʻikoʻi i ka syllabus hoʻokolohua physics o nā kulanui piha a me nā kula ʻenekinia.Hiki i ka hoʻokolohua ke aʻo a hoʻopaʻa i ke ʻano o ke ana ʻana o ka mahina magnetic, hōʻoia i ke kumu superposition o ka māla magnetic, a wehewehe i ka māhele ʻana o ka māla magnetic e like me nā koi aʻo.

E hoʻouna i ka leka uila iā mākou

Maʻiʻo hoʻokolohua nui
1. ka loina o ke ana ana i ka ikaika induction magnetic ma o ka electromagnetic induction.
2. ka nui a me ka puunaue ana o ke kahua magnetic like ole o ka wili poepoe hookahi.
3, ka nui a me ka puunaue ana o ke kahua magnetic o ka Helmholtz coil.

Nā palena ʻenehana nui
1, Helmholtz coil: elua wili like ka nui, radius like 100mm, kaawale waena.
100mm;helu o na huli o ka wili hookahi: 400 huli.
2, ʻelua-dimensional movable non-magnetic anuu, neʻe mamao: ākea ± 130mm, kū pololei ± 50 mm.me ka hoʻohana ʻana i ke alakaʻi non-magnetic, hiki ke neʻe wikiwiki, ʻaʻohe āpau, ʻaʻohe ʻokoʻa hoʻi.
3, ʻike coil: huli 1000, huli ʻana 360 °.
4, ka laulā alapine: 20 a 200Hz, ka hoʻonā alapine: 0.1Hz, ke ana hewa: 1%.
5, ka nalu sine: ka nui o ka volta puka: 20Vp-p kiʻekiʻe, ka amplitude o kēia manawa: 200mA kiʻekiʻe.
6、Ekolu a me ka hapa LED hōʻike kikohoʻe AC millivoltmeter: ākea 19.99mV, ana hewa: 1%.
