According to Fleming's right-hand rule, the index finger and the central finger of the right hand represent directions of ______and _________respectively?

Ainduced current, magnetic field

Bmotion of the conductor, induced current

Cmotion of the conductor, magnetic field

Dmagnetic field, induced current

Answer:

D. magnetic field, induced current

Read Explanation:

  • In fleming's right hand rule, the thumb represents the direction of motion of the conductor, the forefinger represents the direction of magnetic field, and the middle finger represents the direction of the induced current.

  • The thumb points in the direction of the motion of the conductor relative to the magnetic field.

  • The forefinger points in the direction of the magnetic field (from North to South).

  • The middle finger then points in the direction of the induced current in the conductor.
