According to Faraday’s law of electromagnetic induction, when a conductor moves through a magnetic field, an electric current is induced in it.
Fleming’s right-hand rule is used to determine the direction of the induced current.
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.
