Fleming' right-hand rule is used to find out the direction of the current induced in coil due to its rotation in a magnetic field.

According to 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.

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