Question
State the rule to determine the direction of a current induced in a coil due to its rotation in a magnetic field.
Solution
Fleming's Right-Hand Rule, often known as the Dynamo Rule, states that the thumb, first finger and middle finger of the right hand should all be extended so that they are perpendicular to one another. The thumb points in the direction of the conductor's motion, the first (fore) finger points in the direction of the magnetic field, and the central finger points in the direction of the induced current.
