According to Fleming's right-hand rule, if the forefinger indicates the direction of the magnetic field and the thumb shows the direction of motion of the conductor, then the stretched middle finger will predict the direction of

CONCEPT:

• Faraday's Law of electromagnetic induction states that when a conductor moves inside a Magnetic Field, an electric current induces in the conductor.
• Fleming's right-hand rule:
  • According to Fleming's right-hand rule, the thumb, forefinger, and middle finger of the right hand are stretched to be perpendicular to each other and if the thumb represents the direction of the movement of the conductor, the fore-finger represents the direction of the magnetic field, then the middle finger represents the direction of the induced current.
  • It is used used to determine the direction of current in a generator's windings.

​

EXPLANATION:

• From the figure, it is clear that if the forefinger indicates the direction of the magnetic field and the thumb shows the direction of motion of the conductor, then the stretched middle finger will predict the direction of the induced current.

Additional Information

• Fleming's Left-Hand Rule states that if we keep our Fore Finger in the direction of the Magnetic Field, Middle Finger in the direction of the Current then the thumb directs the direction of the Force experienced by the conductor.
