Which of the following law/rule can he used to determine the direction of rotation of D.C. motor ?
Correct answer: D. Fleming's left-hand rule
- A. Lenz's law
- B. Faraday's law
- C. Coloumb's law
- D. Fleming's left-hand rule
Explanation
Fleming's left-hand rule gives the direction of force on a current-carrying conductor in a magnetic field, and therefore determines the direction of motor rotation. Fleming's right-hand rule is used for generator action.
