Mphamvu kumunda: chikhalidwe ndi maonekedwe chachikulu

Munda magetsi, malinga ndi mfundo zachibwanabwana thupi, sichina koma wapadera sing'anga zinthu zikuchitika padziko thupi mlandu zokhudza gulu la zimachitika pakati pa matupi amenewa ndi ena mlingo amalire ndi danga mosamalitsa zochepa.

Iwo kalekale chasonyeza kuti minda magetsi angayambe onse n'kupuma ndi zoyenda Tel. The chizindikiro chachikulu cha kukhalapo izi mtundu wa nkhani ndi kukopa kwake pa milandu magetsi.

Mmodzi wa waukulu kachulukidwe makhalidwe a m'munda magetsi ndi lingaliro "munda mphamvu". Kumbali n'zosangalatsa kumva, akuti izi zikutanthauza chiŵerengero mphamvu kuti amachita pa mlandu mayeso mwachindunji kuchuluka mlandu.

E = F / Q kulima.

chakuti woyang'anira mlanduwu zikutanthauza kuti palibe mbali polenga munda sadzavomereza, ndipo phindu lake ndi wochepa kwambiri kuti sichichititsa kupotoza aliyense wa deta pachiyambi. The mwamphamvu munda amayezedwa V / m, amene ali conventionally wofanana H / C.

Wotchuka English kafukufuku Michael Faraday koyamba njira za sayansi wa mavoti mwatsatanetsatane za m'munda magetsi. Malinga ndi iye, mtundu wapadera wa nkhaniyi zojambula ayenera akuimira mu mawonekedwe a mizere mosalekeza. Iwo anadzatchedwa "mzere magetsi kumunda," ndi malangizo awo, potengera malamulo zofunika lachibadwidwe, chikugwirizana ndi malangizo a mavuto.

mizere ulamuliro wofunika kusonyeza ngati makhalidwe Mkhalidwe wa mavuto ngati osalimba kapena osalimba. osalimba a mphamvu ya mizere zimadalira chiwerengero pa malo unit. Yopangidwa ndi mphamvu mizere chitsanzo kudziwa mawu kachulukidwe mphamvu kumunda ena malo ake, ndi kuphunzira mmene kusintha.

Chochititsa chidwi n'chakuti katundu wa kumunda magetsi a dielectric. Monga amadziwika, dielectrics - nkhani imene pali particles pafupifupi palibe ufulu mlandu, kotero, monga Motero, iwo sangathe kuchititsa magetsi panopa. Zinthu zimenezi ayenera zimachitika makamaka onse mipweya, ziwiya zadothi, dongo ndi madzi otchezedwa, Mica, etc.

Pofuna kudziwa munda mphamvu dielectric, kuyenera kudutsa m'munda magetsi. Mu kanthu zokhudzana milandu zake dielectric anayamba kuimba Komabe, kusiya malire ka tinthu awo, iwo sangathe. Lathu kukondera akusonyeza kuti ndithu mlandu kusuntha mbali ya munda magetsi, ndi moyipa mlandu - motsutsana. Chifukwa cha mwai izi mkati dielectric wamkulu watsopano munda magetsi, zomwe ndi zosemphana ndi chitsogozo cha kunja. Pofunika mkati kwambiri kumachepetsa kunja, kotero mavuto a madontho lomaliza.

Mphamvu kumunda n'kofunika kwambiri kachulukidwe khalidwe lake ndilo mwachindunji malinga ndi mphamvu imene mtundu winawake wa nkhani amachita pa mlandu kunja magetsi. Ngakhale kuti mtengo uwu sungakhoze kuwaona ndi thandizo la mizere mphamvu mavuto a chithunzicho, mukhoza kudziwa kachulukidwe ake ndi lathu mu mlengalenga.
