1. Nguva yekusashanda zvakanaka kwechikamu

Ongorora chidimbu chinotenderera. Chidimbu chine huremu m chinopihwa simba F kuitira kuti chidimbu chitenderere kutenderedza axis O. Chidimbu chacho chakasiyana ne axis yekutenderera. Kutanga, chidimbu chacho chiri pa rest (v = 0). Mushure mekufamba nesimba ra F, zvidimbu zvinofamba nekumhanya kwakati kuti kuitira kuti zvidimbu zvive nekumhanya kwakati. Hukama huripo pakati pesimba (F), huremu (m), uye kukurumidza kwakati kwezvidimbu kunoratidzwa ne equation 3:

Tsanangudzo yemagetsi emagetsi

Mumuchina wekufambisa magetsi wakaita semhangura, mune maerekitironi anofamba zvisina tsarukano nekumhanya kwakanyanya asi asingabude musimbi. Maerekitironi anogona kufamba zvakasununguka anonzi maerekitironi akasununguka. Kunyange zvazvo maerekitironi achifamba zvakasununguka kumativi ese, hapana kuyerera kwemaerekitironi kwakazara munzira yakati. Izvi zvinoitika kana pasina musiyano uripo pakati pemagumo maviri ewaya yemhangura.

Kana waya yakabatana nechinhu chemagetsi, mutsauko ungavapo pakati pemativi maviri ewaya yemhangura, zvekuti munda wemagetsi unoonekwa mukati mewaya yemhangura. Kuvapo kwemunda wemagetsi kunoita kuti maerekitironi akasununguka aone simba remagetsi F = q E = e E, apo F = simba remagetsi , e = electron charge, E = munda wemagetsi . Simba iri remagetsi rinoita kuti maerekitironi ese ari kufamba zvakasununguka amhanye pamwe chete, iro riri divi rimwe chete nesimba remagetsi.

Chinyorwa pamusoro peTsananguro ye capacitor

Tsanangudzo ye capacitor mudziyo unochengetedza chaji yemagetsi uye simba remagetsi. Capacitor iri nyore ine maplate maviri kana masheti anoiswa pedyo asi asingabatane uye anoparadzaniswa neinsulator kana vacuum. Maconductor zvinhu zvinogona kuitisa magetsi zvakaita sesimbi, nepo mainsulator zvinhu zvisingakwanise kuitisa magetsi zvakaita sepurasitiki.

Pakutanga, maconductor maviri aya haana magetsi kana kuti magetsi asina kusimba. Kuti conductor imwe ive nechaji yakanaka uye imwe conductor ive nechaji yakaipa, panofanira kunge paine kutamiswa kwemaerekitironi kubva kune imwe conductor kuenda kune imwe. Maerekitironi ari pamusoro peatomu, saka zviri nyore kufamba. Mushure mekunge maerekitironi afamba kubva kune imwe conductor kuenda kune imwe, imwe ye conductors ine maerekitironi akawanda (kushaya mapurotoni).

zvekuti inochajwa zvisina kunaka, ukuwo imwe kondakita iine kushomeka kwemaerekitironi (proton yakawandisa) zvekuti inochajwa zvakanaka. Tsananguro yakadzama yemaitiro ekuchaja magetsi pamacapacitor inoongororwa pamusoro penyaya yekuchengetedza simba remagetsi mumacapacitor.

Tsanangudzo yesimba remagetsi

Simba remagetsi rinotsanangurwa sesimba remagetsi pachaji imwe neimwe. Ngatitii kana rasvika panhamba a, simba remagetsi q rine simba remagetsi rakaenzana neEP _a , ipapo simba remagetsi panhamba a rinogadzirwa seizvi:

V = simba remagetsi, EP = simba remagetsi, q = kuchaja kwemagetsi

V haisi panzvimbo a chete asiwo panzvimbo dzese dziri mumunda wemagetsi. Poindi a inoshandiswa semuenzaniso. Sezvazvichatsanangurwa gare gare, V haitsamiri pakuchaja q.

Chinyorwa pamusoro pesimba remagetsi

Usati wadzidza nyaya iyi, tanga wanzwisisa basa, masimba anochengetedza, hukama huripo pakati pemasimba anochengetedza ane simba rinogona kuitika , masimba emagetsi nenzvimbo yemagetsi.

Simba remagetsi ndiro simba rekuchengetedza

Kuwedzera kune simba regiravhiti nesimba rechitubu, mumwe muenzaniso wesimba rekuchengetedza isimba remagetsi. Kuti unzwisise zviri nani kuti sei simba remagetsi richinzi simba rekuchengetedza, nzwisisa tsananguro inotevera.

Chinyorwa pamusoro peKuona munda wemagetsi uchishandisa mutemo weGauss

Munda wemagetsi nechaji imwe chete

Kuti uverenge munda wemagetsi unogadzirwa nechaji imwe chete, danho rekutanga nderekusarudza nzvimbo yeGauss yakatenderera ine radius r apo pakati pebhora iri pachaji imwe chete. Nzvimbo yepamusoro yebhora i4πr².

Munda wemagetsi unobuda pakati pedenderedzwa unopinda wakatwasuka pamusoro pedenderedzwa zvekuti fomura yemagetsi inoyerera Φ = E A. Fomura yemutemo waGauss ndeye Φ = Q/ε _o

Chinyorwa pamusoro pemutemo waGauss

Nezvemutemo waCoulomb , simba riri pakati pemagetsi rakadzidzwa. Mukuongorora munda wemagetsi, imwe mhando yemutemo waCoulomb yakakurukurwa, iyo inoratidzwa ne equation F = q E,

apo F iri simba remagetsi, q iri simba remagetsi uye E iri simba remagetsi. Zvinogona kutaurwa kuti mutemo waCoulomb mutemo wefizikisi unotsanangura hukama huripo pakati pesimba remagetsi (q) nesimba remagetsi (E).

Mutemo waGauss mumwe mutemo wefizikisi unotsanangura hukama huripo pakati pemagetsi anochaja neminda yemagetsi. Mutemo waGauss wakagadzirwa naCarl Friedrich Gauss (1777-1855), nyanzvi yefizikisi yedzidziso uye yemasvomhu yekuGermany.

Tsanangudzo yemagetsi anoyerera

Nezvemunda wemagetsi, zvakakurukurwa nezve tsananguro uye equation yemunda wemagetsi inogona kushandiswa kuverenga simba remunda wemagetsi rinogadzirwa nechaji yemagetsi, machaji emagetsi akati wandei kana nekugoverwa kwechaji yemagetsi. Kuverengwa kwesimba remunda wemagetsi rinogadzirwa nechaji yemagetsi kana machaji maviri emagetsi kunogadziriswa zviri nyore uchishandisa fomura yesimba remunda wemagetsi. Kana chiri kuverengerwa chiri simba remunda wemagetsi rinogadzirwa nechaji yemagetsi, kuverenga kwacho kwakaoma kana fomura yesimba remunda wemagetsi ikashandiswa, asi zviri nyore kushandisa mutemo waGauss . Usati wadzidza mutemo waGauss zvakadzama, tanga wanzwisisa kuti flux yemagetsi inoyerera nekuda kwepfungwa yeflux yemagetsi inoshandiswa mumutemo waGauss.
