alleryFleming's left-hand rule gives the direction of:
AMagnetic field around current
BInduced EMF in a coil
CForce on a current-carrying conductor in a magnetic field
DCurrent induced by a changing flux
Answer & Solution
Correct answer: C. Force on a current-carrying conductor in a magnetic field
1. Stretch the thumb, fore-finger and middle-finger of the LEFT hand mutually perpendicular.
2. Fore-finger → field B; middle-finger → current I; THUMB → force F.
3. Used in electric motors to find the direction of the rotating force.
4. Fleming's RIGHT-hand rule is for induced current direction (generators).
