LEEM-1 Helmholtz Coil Magnetic Field Apparatus

Takaitaccen Bayani:

Yana da halaye na mitar mitar siginar tashin hankali da daidaitawar ƙarfin fitarwa.
Helmholtz coil magnetic ma'aunin filin maganadisu yana ɗaya daga cikin mahimman gwaje-gwaje a cikin manhajar gwajin kimiyyar lissafi na manyan jami'o'i da kwalejojin injiniya.Gwajin na iya koyo da ƙware hanyar ma'aunin filin maganadisu mai rauni, tabbatar da ƙa'idar babban filin maganadisu, da bayyana rarraba filin maganadisu bisa ga buƙatun koyarwa.

Babban abun ciki na gwaji
1. ka'idar auna ƙarfin shigar da maganadisu ta hanyar shigar da wutar lantarki.
2. girman da rarraba filin maganadisu mara daidaituwa na madauwari guda ɗaya.
3, girman da rarraba filin maganadisu na Helmholtz coil.

Babban sigogi na fasaha
1, Helmholtz coil: coils biyu na girman iri ɗaya, daidai radius 100mm, tazara ta tsakiya.
100mm;adadin juyi na coil guda: 400 juya.
2, dandali mai motsi mara ƙarfi mai girma biyu, nesa mai motsi: kwance ± 130mm, tsaye ± 50 mm.ta yin amfani da jagorar da ba na maganadisu ba, na iya motsawa da sauri, babu tazara, babu bambancin dawowa.
3, coil ganowa: ya juya 1000, kusurwar juyawa 360 °.
4, kewayon mitar: 20 zuwa 200Hz, ƙudurin mitar: 0.1Hz, kuskuren aunawa: 1%.
5, sine kalaman: fitarwa ƙarfin lantarki amplitude: matsakaicin 20Vp-p, fitarwa na yanzu amplitude: matsakaicin 200mA.
