Which of the following rule is used to determine the direction of rotation of D.C motor?

Which of the following rule is used to determine the direction of rotation of D.C motor?

Right Answer is:

Fleming’s Left-hand Rule

SOLUTION

  • When a current-carrying conductor such as a wire attached to a circuit moves placed in a magnetic field, an electric current is induced in the wire due to Faraday’s law of induction.
  • The right hand is held with the thumb, first finger, and second finger mutually perpendicular to each other than
  • The thumb is pointed in the direction of the motion of the conductor relative to the magnetic field i.e direction of the force.
  • The forefinger is pointed in the direction of the magnetic field.
  • The middle finger represents the direction of the induced or generated current within the conductor.
