Isiqondiso se-magnetic flux esikhiqizwa yi-magnet ehlala njalo sisuka ku-N-pole siye ku-S-pole.

Uma umqhubi efakwa ensimini yamagnetic kanye nokugeleza kwamandla kagesi kumqhubi, insimu yamagnetic kanye namandla kagesi kuyasebenzisana ukuze kukhiqizwe amandla. Amandla abizwa ngokuthi “amandla kagesi”.

Umthetho wesandla sobunxele sikaFleming unquma isiqondiso samandla kagesi, amandla kazibuthe kanye nokushintshashintsha komoya. Yelula isithupha, umunwe wokukhomba kanye nomunwe ophakathi wesandla sakho sobunxele njengoba kuboniswe ku-Fig. 2.

Uma umunwe ophakathi kungumbane kanti umunwe wokukhomba ungukugeleza kwamagnetic, isiqondiso samandla sinikezwa yisithupha.

2. Insimu ye-Magnet ekhiqizwa yi-current

3）。Amasimu kazibuthe akhiqizwa yi-current kanye nama-unomphela asebenza ukukhiqiza amandla kagesi.

Uma ugesi ugeleza kumqhubi ubheke kumfundi, insimu yamagnetic ohlangothini lwe-CCW izokhiqizwa ngokuzungeza ugesi ngomthetho wesikulufu osebenzisa isandla sokudla (Umfanekiso 3).

3. Ukuphazamiseka komugqa wamandla kazibuthe

Amasimu kazibuthe akhiqizwa yi-current kanye nama-unomphela ayaphazamisana.

Umugqa wamandla kazibuthe osatshalaliswa ohlangothini olufanayo usebenza ukwandisa amandla awo, kuyilapho ukugeleza osatshalaliswa ohlangothini oluphambene kusebenza ukunciphisa amandla awo.

4. Ukukhiqizwa kwamandla kagesi

Umugqa wamandla kazibuthe unemvelo yokubuyela emgqeni oqondile ngokucindezela kwawo njengebhande elinwebekayo.

Ngakho-ke, umqhubi uphoqeleka ukuba asuke lapho amandla kazibuthe enamandla khona aye lapho ebuthakathaka khona (Umfanekiso 5).

6. Ukukhiqizwa kwe-torque

Amandla kagesi atholakala kulesi sibalo;

Isithombe 6 sibonisa i-torque etholakala lapho kufakwa umqhubi we-single-turn ku-magnetic filed.

I-torque ekhiqizwa ngumqhubi oyedwa itholakala ku-equation;

I-T'(torque)

F (amandla)

R (ibanga ukusuka enkabeni kuya kumqhubi)

Lapha, kukhona abaqhubi ababili abakhona;
