History
John Ambrose Fleming, an English electrical engineer, is credited with inventing the Fleming right-hand rule in the late 19th century. The thumb, index finger, and middle finger of the left hand are used in the right-hand rule.
Statement and Definition
Flemings right hand rule gives the direction of induced current set up in a conductor moving perpendicular to a magnetic field and can be stated as follows:
If we stretch the thumb and the first two fingers of our right hand in mutually perpendicular directions and if the forefinger points in the direction of the magnetic field, thumb in the direction of motion of the conductor; then the central finger points in the direction of current induced in the conductor.
This rule is also called the dynamo or generator rule and has wide practical applications.
Application
Fleming’s right-hand rule is used for electric generators.
