Ndi mphamvu Lorentz Kodi

Kodi mphamvu Lorentz? Kulingalira mtundu wa chilengedwe zomwe zafala mzere mwamphamvu za kuthengo mu atomu. Mukaika m'dera limeneli aliyense mlandu magetsi (zingakhale monga maziko tinthu ndi thupi adawalamulira), ndiye kudzapatsidwa kwa mphamvu ya F amatchedwa "Lorentz mphamvu". Imodzi mwa mfundo zikuluzikulu - ndi kukhalapo kwa tinthu mathamangitsidwe. M'mawu ena, mlandu ndi makina. Pali chilinganizo cha mtima n'zosangalatsa kumva kufunika kwake panopa:

F = Q * (E + ((1 / c) * v) * B),

kumene Q - mlandu; E - mphamvu ya m'munda magetsi; B - maginito mphamvu; ndime - mathamangidwe wa tinthu onyamula mlandu; C - zonse kuwala kumayendera.

Izi ndi chimodzi cha zithunzi za. Pali zovuta zambiri mukuzilemba izo, kulola kuti aone zomwe ndi mphamvu Lorentz, malangizo zamoyo zina ndi maluso awo, kuphatikizanso.

Monga tanenera kale (ndi aona kuchokera kwa mitunduyi ndi), pamafunika kuyenda. Popeza kuti mlandu kayendedwe chifukwa mogwirizana ake ndi munda pali la EMF (electromotive mphamvu). Ndipo zilibe kanthu chimene chikhalidwe cha mmene, kuyambitsa gulu (yokoka mlanduwo kanthu pa wina ndi mnzake ndi zina zotero.).

Poyerekeza ndi zochita zina, Lorentz mphamvu mwachindunji chilamulira chikhalidwe ndi mfundo za Lenz ndi phunziro kwa malamulo ake. Kumbukirani akamanena za mtsogolo. The kanthu anagwira ndi mphamvu electromotive pa mlandu avundulidwe m'munda, nthawi zonse zochokera mu njira yotero (ndi vekitala kuchuluka), kupewa kusintha kulikonse mu mathamangitsidwe.

Amene anganene kuti mphamvu Lorentz anatsimikiza mtima mogwirizana Coulomb milandu ndi zigawo ziwiri zina kugwirizana ndi chisonyezo cha - anakopa maginito ndi magetsi kumunda mphamvu. Childs, mfundo za ndondomeko za ntchito chitsanzo zotsatirazi: mu ndi maginito ndi kupatsidwa ulemu zamoyo zina B pali gawo wochititsa kutalika L ndi malo mtanda yachigawo S, imene magetsi inawadutsa I. Last mwachindunji zimadalira kuchuluka kwa Q mlandu zonyamulira kudutsa buku wagawo kwa nthawi yeniyeni ( ie, pa liwiro v). Choncho, mphamvu chofunika (Lorentz) ndi chiŵerengero cha mphamvu zakunja zimakhudza aliyense chonyamulira woyang'anira mu buku kuperekedwa kwa chiwerengero cha ochititsa mlandu.

Ngati tikambirana zedi vekitala, ndi mphamvu Lorentz ali nthawi zonse anawauza perpendicular malangizo ndi liwiro kupatsidwa ulemu. N'zosavuta kudziwa lathu, ngati ife ntchito odziwika Kumanzere ulamuliro. Kuti tichite zimenezi, maganizo m'dzanja la kudzanja lake lamanzere anaika pafupi ndi wochititsa kuti zala zinayi kusonyeza malangizo amene magetsi utuluke zatsopano ndiponso vekitala za kuthengo kupatsidwa ulemu anauzidwa perpendicular kwa pachikhatho cha. Chifukwa cha chala chachikulu (mlingo woyenerera ndi enawo) tilongosolere kuti mchitidwe mphamvu vekitala pa milandu. Imodzi mwa mbali ya mphamvu kuti chingasinthe yekha malangizo a mathamangidwe ndi vekitala aliyense wa particles ndi mlandu, ngakhale kusintha mphamvu za kayendedwe (kayendedwe mphamvu).

Patapita nthawi pambuyo kutsegula inapezeka, ndi kugwiritsa ntchito mphamvu Lorentz. Mmodzi wa anthu otchuka kwambiri - mawonekedwe ake mu zotsatira Hall. Chifukwa mu zodabwitsazi kuchepetsa zikachitika, ndi maonekedwe a mlandu angathe bwalolo conductive (riboni). Zotsatira Hall chimagwiritsidwa ntchito zipangizo zosiyanasiyana chingwe ndi masensa. Komanso Dziwani ndi mfundo za ntchito CRT CRT kuti amagwiritsa kuchimwa zotsatira mbali maginito kuyendera particles mlandu panamveka ndi maelekitirodi ndi ( "mfuti") kwa ma elekitironi TACHIMATA phosphor pamwamba ndi anapanduka ndi mfundo amene ndondomeko amadziwika ndendende chifukwa mizere mogwirizana kumunda ndi mlandu kusuntha particles .
