Chii Lorentz simba

Chii Lorentz simba? Fungidzira kuti mumhoteredzo mhando hwakazara mutsetse kusimba ari remagetsi munda. Kana ukaisa munharaunda iyi chero yemagetsi vebasa (zvinogona sezvo chepuraimari PARTICIPLE uye mhosva muviri), ipapo uchapiwa matambudziko ari F, rinonzi "Lorentz simba". Imwe pfungwa huru - ndiyo pamberi PARTICIPLE kumhanyisa. Nemamwe mashoko, nokuchengeta iri chinjwa. Pane nzira kuti nhamba kutsunga ayo ukoshi kuitika:

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

apo Q - vatariri; E - kusimba yemagetsi munda; B - remagineti simba; V - velocity of PARTICIPLE akatakura vebasa; C - kuramba kumhanya chiedza.

Uyu unongova mumwe kumifananidzo. Pane kunzwisisa zvikuru kukunyorerai nayo, vachibvumira kusarudza chii Lorentz simba, mirayiridzo vectors uye zvinogonekwa dzavo Panewo.

Sezvambotaurwa (uye ndaona kubva Masvomhu), zvinokosha kufamba. Chokwadi kuti mhosva sangano nokuda kudyidzana dzaro munda pane kuti EMF (electromotive simba). Uye hazvina basa chii hunhu matambudziko, kumharuro kufamba (giravhiti, mhosva kuita pane mumwe uye zvichingodaro.).

Ichienzaniswa nedzimwe maitiro, kuti Lorentz hondo correlated zvakananga chete pakutaura pamusoro Lenz uye pasi mitemo yayo. Yeuka musimboti yokupedzisira. The chiito kwakakonzerwa ne electromotive simba pamusoro kubvongodzwa mutariri mumunda, nguva dzose nezvatinovavarira nenzira yakadaro (ndiwo Vector uwandu), kudzivisa chero kuchinja kumhanyisa.

Mumwe anogona kuti Lorentz simba iri pakutsvaga Coulomb kudyidzana mhosva uye vaviri mamwe zvinoriumba chokuita inofamba pakati - unochinja kuti rinobva uye yemagetsi munda simba. Kazhinji, nokuti tsananguro kwemasayendisiti uchishandisa zvinotevera muenzaniso: mune imwe remagineti pamwe induction vectors B pane chidimbu kondakita pakureba L uye muchinjikwa-sectional nharaunda S, uhwo Magetsi I. Last zvakananga kunoenderana uwandu Q muripo vatakuri achipfuura chikwata vhoriyamu kwenguva chaiyo ( kureva, pane imwe kumhanya v). Nokudaro, zvaida simba (Lorentz) ndiyo nhamba iri zvokunze simba, kukanganisika mumwe mutakuri mutariri pamamiriro vhoriyamu nokuwanda muripo conductors.

Kana tikafunga Vector kwazvo, kuti Lorentz simba nguva dzose rinotungamirirwa perpendicular nokutungamirira uye kumhanya induction. Zviri nyore chaizvo kuti asarudze dzidziso dzayo, kana tikashandisa anozivikanwa kuruboshwe-ruoko utongi. Kuti aite izvi, mupfungwa emichindwe ruoko rwake rworuboshwe akaisa pedyo muitisi kuitira kuti minwe mina inoratidza nhungamiro umo Magetsi Rwako, uye Vector pamusoro induction munda raitungamirirwa perpendicular kuti muchanza. Somugumisiro napagumwe roruoko (kurudyi pakona nevamwe) achaita kunongedzera simba Vector chiito pamusoro mhosva. Mumwe zviri simba iri kuti anoshandura chete vatungamirire velocity Vector rimwe nerimwe mhosva nezvimedu, apo haana kuchinja nesimba inofamba (kinetic simba).

Pashure pashure kuvhurika yakawanikwa, uye kushandiswa Lorentz simba. Chimwe chezvinhu akakurumbira - zviri kuratidzwa yaro mugumisiro Hall. Nokuda nawo ichi zvaizopedza Fani kunoitika, uye chitarisiko zvinogona vebasa pamusoro conductive mundiro (Ribbon). Kuvhiringidzwa Hall iri zvinowanzoshandiswa siyana kuyera mano uye sensors. Uyewo kucherechedza ndiwo musimboti kushanda CRT CRT kuti inoshandisa Kutsauka mugumisiro achitaura remagineti nezvekubva mhosva nezvimedu chaibwinya ne electrodes ( "pfuti") nokuda maerekitironi zvemapuranga phosphor pamusoro vari vakatsauka kuti pfungwa ane Coordonatele dzinozivikanwa chaiyo nokuda kukurukurirana munda mitsetse uye mutariri zvinokambaira nezvimedu .
