Question
The direction of rotation of a coil in an electric motor is determined by the _____.
- Fleming’s right-hand rule
- Fleming’s left-hand rule
- Faraday law of electromagnetic inductors
- None of above
Hint:
- The direction of rotation of a coil in an electric motor is determined by Fleming's left-hand rule
The correct answer is: Fleming’s left-hand rule
- The direction of rotation of a coil in an electric motor is determined by Fleming's left-hand rule
- Fleming's left-hand rule determines the direction of the force on a wire. When a coil of current-carrying wire rotates due to its presence in a magnetic field, this is known as the motor effect
- Fleming’s Left Hand Rule states that if we arrange our thumb, forefinger and middle finger of the left hand perpendicular to each other, then the thumb points towards the direction of the magnetic force, the forefinger points towards the direction of the magnetic field and the middle finger points towards the direction of the current
