Yadda behaves electrically caje barbashi a lantarki da kuma Magnetic filayen?

Electrically caje barbashi - a barbashi, wanda yana da kyau ko korau cajin. Wannan na iya zama ko dai kwayoyin halitta, kwayoyin ko na farko barbashi. Lokacin da barbashi aka electrically caje a cikin wani lantarki filin, Coulomb karfi ayyukan a kan shi. A darajar wannan karfi, idan kun san filin tsanani , a kuma wani lokaci, aka lasafta ta da wadannan dabara: F = QE.

Saboda haka, mun ƙaddara cewa electrically caje barbashi, wanda shi ne a cikin wani lantarki filin, motsa a ƙarƙashin rinjayar da Coulomb karfi.

Yanzu la'akari da Hall sakamako. Gwaje, an gano cewa Magnetic filin rinjayar da motsi na cajin barbashi. Magnetic shigar da shi ne da matsakaicin karfi da abubuwa a kan gudun irin wannan barbashi da Magnetic filin. A caje barbashi motsi da gudu. Idan electrically caje barbashi zai tashi a wani Magnetic filin a daidan gudun, da karfi wanda abubuwa a kan wani ɓangare na filin ne perpendicular zuwa gudu daga cikin barbashi da Magnetic shigar da vector daidai da: F = q [v, B]. Tun da karfi da cewa abubuwa a kan barbashi motsi ne perpendicular zuwa gudu, da kuma cikin hanzari, kamar yadda aka ba da wannan karfi perpendicular zuwa motsi, cikin hanzari ne na al'ada. Haka kuma, a mike hanyar motsi ne lankwasa a lamba tare da wata tuhuma barbashi a wani Magnetic filin. Idan barbashi shiga layi daya da Lines na Magnetic shigar da, da Magnetic filin ba aiki a kan cajin barbashi. Idan ta shiga perpendicular zuwa Lines na Magnetic shigar da, da karfi aiki a kan barbashi ne a wani matsakaicin.

Yanzu mun rubuta II Newton ta dokar: qvB = mv ² / R, ko R = mv / qB, inda m - shi ne taro na wani caje barbashi, kuma R - da radius daga cikin yanayin. Daga wannan lissafi shi ya bi da cewa barbashi motsa a cikin kama filin daga a da'irar radius. Saboda haka, lokaci na dabam dabam na wani caje barbashi ne mai zaman kanta da circumferential gudun motsi. Ya kamata a lura da cewa electrically caje barbashi makale a cikin Magnetic filin, da sanadin motsi makamashi ne canzawa. Saboda karfi ne perpendicular zuwa tashin barbashi a wani daga cikin yanayin da maki, da ƙarfin da Magnetic filin da abubuwa a kan barbashi ba yi da aikin hade da motsi da cajin barbashi.

Shugabanci na karfi exerted a kan motsi na a caje barbashi a wani Magnetic filin za a iya ƙaddara da "dokoki na hagu." Domin wannan shi ne zama dole ga matsayi hagu haka cewa hudu yatsunsu nuna shugabanci na gudu daga a caje barbashi, da kuma Magnetic shigar da Lines an directed a cikin dabino cibiyar, a cikin wannan yanayin tankwasa a 90 digiri thumb zai nuna shugabanci na karfi da abubuwa a kan gaskiya ma caje barbashi. A wannan yanayin, idan barbashi yana da wani mummunan cajin, da karfi shugabanci zai zama kishiyar.

Idan electrically caje barbashi cewa fada cikin yankin na hadin gwiwa mataki na Magnetic da lantarki filayen, shi ne mai karfi, da ake kira Lorentz karfi: F = QE + q [v, B]. A karon farko a wannan harka da dangantaka da wani lantarki bangaren, da kuma na biyu - da Magnetic filin.
