Sidee u dhaqmo koronto eedeeyay walxaha beeraha korontada iyo magnetic?

Koronto eedeeyay walxaha - walxaha a, taas oo uu leeyahay lacag togan ama taban. Tani waxay noqon kartaa mid atamka, taagoo ama qayb ka hoose. Marka walxaha la koronto eedeeyay duurka koronto, falalka xoog Coulomb waxa on. Qiimaha ciidanka this, haddii aad taqaan xoogga beerta barta gaar ah, waxaa loo xisaabiyaa by formula soo socda: F = QE.

Sayidka, waxaan goostay in walxaha koronto eedeeyay, taas oo ah in beerta koronto, sarkhaansan xoog Coulomb guuro.

Haddaba ka fiirsada saamayn Hall ah. Experimentally, waxaa la ogaaday in duurka ku magnetic saamayn ku mooshinka qayb eedeeyay. induction magnetic waa xoog badnaan, taas oo u dhaqmo on xawaaraha walxaha noocan oo kale ah ay duurka ku magnetic. walxaha A eedeeyay xawaare dhaqaaqin. Haddii qayb ka koronto eedeeyay duuli doonaa beer magnetic xawaare ka dejiyay, ciidanka oo u dhaqmo on qayb ka mid ah beerta ku waa dadab iyo in ay xawaare ka mid ah walxaha iyo dulinka ah induction magnetic siday u kala horreeyaan, F = q [v, B]. Tan iyo markii ciidamada in u dhaqmo on mooshin walxaha waa dadab iyo in ay xawaare ku, iyo xawaaraha, sida la siiyey xoog this dadab iyo in ay mooshinka, dardargelinta waa caadi. Iyadoo la raacayo, ee si toos ah jidka dhaqdhaqaaqa waa wada xodan yihiin xiriir la walxaha lagu soo oogay in beer magnetic. Haddii ay qayb galo barbar socda laymanka of induction magnetic, ay duurka ku magnetic uusan u dhaqmaan on walxaha ku amray ma. Haddii gashey dadab iyo in ay khadadka induction magnetic, ciidanka simaha on walxaha waa ugu badnaan.

Hadda waxaan u qori II sharciga Newton ee: qvB = MV ² / R, ama R = MV / QB, halkaas oo m - waa tiro ka mid ah walxaha lagu soo oogay, iyo R - gacan ka mid ah dhabbihii. From isla'egta this waxaa soo socota in ay qayb ka dugaagga duurka jooga oo dhqaalaha of goobada ka mid ah gacan. Sidaas darteed, muddada wareegga of walxaha lagu soo oogay ka madax bannaan yahay xawaaraha circumferential dhaqdhaqaaqa. Waa in la ogaadaa in ay qayb ka koronto eedeeyay xanniban duurka ku magnetic, tamarta ogeed waa iska beddelin. Maxaa yeelay, ciidanka waa dadab iyo in ay mooshin ka qayb kasta oo ka mid ah dhibcood dhabbihii, xoogga duurka magnetic oo u dhaqmo on walxaha ma qabtaan shaqada la xiriira dhaqaaqin walxaha ku amray.

jihada ciidamada balaaran on mooshinka ka mid ah walxaha lagu soo oogay in beer magnetic la go'aamin karaa by the "xeerarka gacanta bidix." Waayo, kan waxaa muhiim ah in dhig gacanta bidix si ay afar farood ku fiiqaya jihada of xawaare ka mid ah walxaha lagu soo oogay, si fiican oo khadadka induction magnetic waxaa si toos ah xarunta timirta ah, haddii ay taasi ka qaloocsan tahay 90 darajo suulka ku tusi doonaa dhinaca ciidamada ah oo u dhaqmo on wanaagsan ee walxaha eedeeyay. Haddii ay sidaa tahay, haddii walxaha leeyahay amar diidmo ah, jihada ciidamada uu noqon doono mid ka soo horjeeda.

Haddii qayb ka koronto eedeeyay in ku dhacaa goobta ka maqnaa wadajirka ah ee beeraha magnetic iyo korontada, waa ciidan, u yeedhay ciidanka Lorentz ah: F = QE + q [v, B]. Ereyga ugu horreeya ay dhacdo in tani ay la xidhiidho qayb korontada, iyo tan labaad - duurka u magnetic.
