Icala le-magnetic flux eliveliswa yi-magnet esisigxina lihlala lisuka kwi-N-pole ukuya kwi-S-pole.

Xa umqhubi ebekwe kwindawo enemagnethi kwaye umsinga ungena kwi-conductor, intsimi enemagnethi kunye nomsinga ziyasebenzisana ukuvelisa amandla. Amandla abizwa ngokuba yi-“electromagnetic force”.

Umthetho wesandla sasekhohlo sikaFleming umisela icala lombane, amandla emagnethi kunye ne-flux. Yolula ubhontsi, umnwe wokukhomba kunye nomnwe ophakathi wesandla sakho sasekhohlo njengoko kubonisiwe kuMfanekiso 2.

Xa umnwe ophakathi ungumbane kwaye umnwe wesalathisi ungumbane ojikelezayo, ulwalathiso lwamandla lunikwa ngubhontsi.

2. Intsimi yemagnet eveliswe yi-current

3）。Amasimi emagnethi aveliswa yimagnethi yangoku kunye neemagnethi ezisisigxina asebenza ukuvelisa amandla e-electromagnetic.

Xa umsinga ungena kwi-conductor usiya kumfundi, intsimi yemagnethi kwicala le-CCW iya kuveliswa ijikeleze umsinga ngomthetho wesikrufu osebenzisa isandla sasekunene (Umzobo 3).

3. Ukuphazamiseka komgca wamandla emagnethi

Amasimi emagnethi aveliswa yi-current kunye neemagnethi ezisisigxina ziyaphazamisana.

Umgca wamandla emagnethi asasazwa kwicala elinye usebenza ukwandisa amandla awo, ngelixa ukujikeleza okusasazwa kwicala elichaseneyo kusebenza ukunciphisa amandla awo.

4. Imveliso yamandla e-electromagnetic

Umgca wamandla emagnethi unesimo sokubuyela kumgca othe tye ngokuxinezeleka kwawo njengebhanti elastiki.

Ngoko ke, umqhubi unyanzelekile ukuba asuke apho amandla emagnethi anamandla khona aye apho abuthathaka khona (Umz. 5).

6. Imveliso yeTorque

Amandla e-electromagnetic afunyanwa kwi-equation;

Umzobo 6 ubonisa i-torque efunyenweyo xa kufakwa umqhubi we-single-turn kwi-magnetic filed.

I-torque eveliswa ngumqhubi omnye ifunyanwa kwi-equation;

T'(torque)

F (amandla)

R (umgama ukusuka embindini ukuya kumqhubi)

Apha, kukho abaqhubi ababini abakhoyo;
