Flemings right-hand rule is a principle used in electromagnetism to determine the direction of induced current when a conductor attached to a circuit moves in a magnetic field. It is particularly useful in determining the direction of current in a generators windings. The rule involves holding the right hand with the thumb, index finger, and middle finger mutually perpendicular to each other. The thumb points in the direction of the motion of the conductor relative to the magnetic field, the index finger points in the direction of the magnetic field, and the middle finger points in the direction of the induced or generated current within the conductor.
Flemings right-hand rule is an important concept in the study of electromagnetism and is widely used in the analysis of generators and electromagnetic induction.
