Isixhobo seMagnetic Field se-LEEM-1 Helmholtz Coil

Inkcazo emfutshane:

Ineempawu ze-variable frequency yesignali yokuvuselela kunye nobungakanani bemveliso elungisekayo.
Ukulinganisa intsimi yemagnethi yekhoyili yeHelmholtz yenye yezona zilingo zibalulekileyo kwisilabhasi yovavanyo lwefiziksi kwiiyunivesithi ezibanzi nakwiikholeji zobunjineli. Olu vavanyo lunokufunda kwaye luyiqonde kakuhle indlela yokulinganisa intsimi yemagnethi ebuthathaka, lungqine umgaqo we-superposition yentsimi yemagnethi, kwaye luchaze ukusasazwa kwentsimi yemagnethi ngokweemfuno zokufundisa.

Iithegi zeMveliso

Umxholo ophambili wovavanyo
1. umgaqo wokulinganisa amandla okungenisa amandla emagnethi ngokungenisa amandla e-electromagnetic.
2. ubungakanani kunye nokusasazwa kwentsimi yemagnethi engalinganiyo yekhoyili enye ejikelezayo.
3, ubungakanani kunye nokusasazwa kwentsimi yemagnethi yekhoyili yeHelmholtz.

Iiparameter eziphambili zobugcisa
1, ikhoyili yeHelmholtz: iikhoyili ezimbini ezinobukhulu obufanayo, irediyasi elinganayo eyi-100mm, isithuba esiphakathi.
100mm; inani lokujika kwekhoyili enye: ukujika okungu-400.
2, iqonga elinombane elinokushukuma elinamacala amabini, umgama oshukumayo: tye ± 130mm, ngokuthe nkqo ± 50 mm. Ukusebenzisa isikhokelo esingenambane, kunokushukuma ngokukhawuleza, akukho sithuba, akukho mahluko wokubuya.
3, ikhoyili yokufumanisa: ijika ibe yi-1000, i-engile yokujikeleza ibe yi-360 °.
4, uluhlu lweefrikhwensi: 20 ukuya kwi-200Hz, isisombululo sefrikhwensi: 0.1Hz, impazamo yokulinganisa: 1%.
5, i-sine wave: i-output voltage amplitude: ubuninzi be-20Vp-p, i-output current amplitude: ubuninzi be-200mA.
6. Isiboniso sedijithali se-LED esineemitha ezintathu ezinesiqingatha se-AC: uluhlu lwe-19.99mV, impazamo yokulinganisa: 1%.
