__________ rule is used to know the direction of an induced current in the circuit.

As we know from Faraday's law that a current induces in a conductor whenever conductor is moving through a magnetic field.

Fleming' right hand rule is use to find out the direction of the induced current within a conductor, when the conductor is moving in a magnetic field.

•According to the Fleming’s right hand rule, if we put our thumb, index finger and middle finger mutually perpendicular to each other.

•Such that thumb points in the direction of the motion of conductor and index finger point in the direction of the applied magnetic field. The given picture illustrates the rule:

•Then middle/centre finger will show the direction of the induced or generated current within the conductor.
