Muenzaniso wemagetsi anoyerera

Mienzaniso mina yeMatambudziko eMagetsi eFlux

1. Munda wemagetsi ye 8000 N/C yakatarisana nepamusoro pe square ine nharaunda ye 10 m²Sarudza kuyerera kwemagetsi iyo inopfuura nepanzvimbo ine sikweya!
Kukurukurirana
Zvinozivikanwa kuti:
Munda wemagetsi (E) = 8000 N/C
Nzvimbo yepamusoro (A) = 10 m²
θ = 0^o (mitsara yemagetsi inoenderana nemitsetse yakajairika)
Akabvunzwa: Kuyerera kwemagetsi (Φ)
Mhinduro:

Fomura yekuyerera kwemagetsi:

Φ = EA cos θ
Tsanangudzo: Φ = electric flux (Nm)²/C), E = munda wemagetsi (N/C), A = nzvimbo yepamusoro (m²), θ = kona iri pakati pemutsetse wemagetsi nemutsetse wakajairika (mutsetse wakatarisana nepamusoro).

Hukuru hwemagetsi anoyerera:

Φ = EA cos θ = (8000)(10)(cos 0) = (8000)(10)(1) = 80.000 = 8 x 10 ⁴ Nm ² /C

2. Simba remagetsi re5000 N/C rinopfuura nepanzvimbo ine sikweya uye rinoumba kona ye60^o kusvika pamutsetse wakajairika. Nzvimbo yepamusoro pechikwere i2 m²Tsvaga kuti magetsi ari kufamba sei nepanzvimbo ine sikweya!
Kukurukurirana
Zvinozivikanwa kuti:
Munda wemagetsi (E) = 5000 N/C
Nzvimbo yepamusoro (A) = 2 m²
θ = 60^o
Akabvunzwa: Kuyerera kwemagetsi (Φ)
Mhinduro:
Kuyerera kwemagetsi:
Φ = EA cos θ = (5000)(2)(cos 60) = (5000)(2)(0,5) = 5000 = 5 x 10³ Nm²/C

3. Simba remagetsi re4000 N/C rinopfuura nepamusoro pebhokisi sezvakaratidzwa mumufananidzo uri pazasi. Bhokisi iri rakareba mamita maviri, rakafara mita imwe, uye rakareba mita imwe. Sarudza kuti flux yemagetsi inopfuura nepabhokisi!

Kuyerera kwemagetsi nepakati pebhuroko

Zvichibva pamufananidzo, mitsetse yemagetsi ine ruvara rutsvuku yakatarisana nepamusoro pechivharo kuitira kuti ienderane nemutsetse wakajairika (ichiumba kona ye0 ^o ), nepo mimwe mitsetse yemagetsi yakatarisana nepamusoro kuitira kuti ive yakatarisana nemutsetse wakajairika (ichiumba kona ye90 ^o ).

Mitsetse yemagetsi mitsvuku inopinda mubhuroko asi ichienda kunze kubva mariri. Kana mitsetse yemagetsi ichipinda mubhuroko, zvinoita sekunge mune negative charge mukati mebhuroko, saka electric flux inenge iri negative. Kusiyana neizvi, kana mitsetse yemagetsi ichienda kunze kubva mubhuroko, zvinoita sekunge kune positive charge mukati mebhuroko, saka electric flux inenge iri positive. Mitsetse yemagetsi inopinda mubhuroko yakafanana nemitsetse yemagetsi inopinda mubhuroko, saka electric flux inobva pairi izero.

4. Bhora rine dhayamita ye 0,5 uye pakati pebhora pane charge yemagetsi ye 10 μC. Tsvaga kuti flux yemagetsi iri kupi nebhora!

Zvinozivikanwa kuti:
Radiyo yebhora (r) = 0,5 metres
Chaja yemagetsi (Q) = 10 μC = 10 x 10^-6 C
Akabvunzwa: Kuyerera kwemagetsi (Φ)
Mhinduro:

Munda wemagetsi:

E = kq/r²
E = (9 x 10)⁹ Nm²/C²)(10 x 10^-6 C) / 0,5²
E = (90 x 10)³/ 0,25
E = 360 x 10³
E = 3,60 x 10⁵ N / C.

Nzvimbo yepamusoro yebhora:

A = 4 π r ² = 4 (3,14) (0,5) ² = (12,56) (0,25) = 3,14 ^m2

Kuyerera kwemagetsi:

Mitsetse yemagetsi yakatwasuka pamusoro uye inowirirana nemutsetse wakajairika zvekuti kona yakagadzirwa i0^o.
Φ = EA cos θ
Φ = (3,60 x 10⁵)(3,14)(cos 0)
Φ = (11,304 x 10⁵)(1)
Φ = 11,304 x 10⁵
Φ = 1,13 x 10⁶ Nm²/C
