Fleming's left hand rule gives the direction of

  • A. the induced current in a generator
  • B. the force on a current carrying conductor in a magnetic field
  • C. the magnetic field around a wire
  • D. the induced emf

Explanation

With the first finger along the field and the second along the current, the thumb gives the motion or force, which is the motor rule. The right hand rule is the generator rule, giving the direction of an induced current. Remembering that left is for motors and right is for generators avoids most of the confusion here.
