Ulwalathiso lwe-magnetic flux eveliswa nguzibuthe osisigxina luhlala lusuka kwi-N-pole ukuya kwi-S-pole.

Xa i-conductor ifakwe kwintsimi yamagnetic kunye nokuhamba kwangoku kwi-conductor, i-magnetic field kunye ne-current isebenzisana ukuze ivelise amandla. Amandla abizwa ngokuba yi "Electromagnetic force".

Umthetho wesandla sasekhohlo sika-fleming umisela isalathiso sangoku, amandla kazibuthe kunye ne-flux. Yolula ubhontsi, umnwe wesalathisi kunye nomnwe ophakathi wesandla sakho sasekhohlo njengoko kubonisiwe kumfanekiso wesi-2.

Xa umnwe ophakathi ukhoyo kwaye umnwe wesalathisi i-flux yamagnetic, isalathiso samandla sinikezelwa ngesithupha.

2.Indawo yemagnethi eveliswe ngoku

3)

Xa i-current flowing in conductor towards the reader, i-magnetic field in CCW direction will be produced around the current flow by the right-handed screw rule (Fig.3).

3.Ukuphazamiseka komgca wamandla kazibuthe

Iimagnethi eziveliswa ngoku kunye neemagnethi ezisisigxina ziyaphazamisana.

Umgca wamandla kazibuthe osasazwe kwicala elifanayo wenza ukwandisa amandla ayo, ngelixa i-flux esasazwa kwicala elichaseneyo yenza ukunciphisa amandla ayo.

4.Imveliso yamandla ombane

Umgca wamandla kazibuthe unendalo yokubuyela kumgca othe tye ngokuxinana kwawo njengebhanti elastiki.

Ngaloo ndlela, umqhubi unyanzelekile ukuba ahambe ukusuka apho amandla amagnetic anamandla ukuya apho abuthathaka khona (Fig.5).

6.Imveliso yeTorque

I-electromagnetic force ifumaneka kwi-equation;

Umzobo we-6 ubonisa i-torque efunyenweyo xa i-conductor-turn-turn ifakwe kwifayile yamagnetic.

I-torque eveliswa ngumqhubi omnye ifunyenwe kwi-equation;

T'(torque)

F (force)

R (umgama ukusuka embindini ukuya kumqhubi)

Apha, kukho abaqhubi ababini abakhoyo;
