Fleming’s Right hand rule is used to find the direction of induced emf and hence the direction of current
when a conductor moves at right angles to a stationary magnetic field.
Fleming’s Right hand rule is stated as “ Stretch out the forefinger, middle finger and thumb of your right hand so that they are mutually
perpendicular to each other. If forefinger points in the direction of magnetic field, thumb
in the direction of motion of the conductor, then the middle finger will point
in the direction of flow of induced current”.
