What is Fleming’s Right Hand Rule ?

Fleming’s Left Hand Rule is Rule for Finding the Direction Of Rotation of an Electric motor.

It show the relation between the direction of thrust on a conductor carrying a current in magnetic field.


Let us discuss in brief

There will be a force acting on the conductor whenever a current carrying conductor comes under a magnetic field. The direction of this force can be found using Fleming’s Left Hand Rule (also known as the’ Fleming’s left-hand rule for motors’).

Similarly if a conductor is forcefully brought under a magnetic field, that conductor will have an induced current. One can find the direction of this force using the Fleming’s Right Hand Rule.


What it states

Fleming’s Right Hand rule states that if we point the index finger, middle finger and the thumb perpendicularly with the thumb pointing in the direction of motion of conductor and the index finger along the magnetic field, then the middle finger points in the direction of induced current.


How to use

Keeping the Thumb,Index Finger and Middle figure of the Left Hand at perpendicular to each other with the thumb pointing in the direction of motion of conductor and the index finger along the magnetic field, then the middle finger points in the direction of induced current.

Thumb :-Direction of Thrust or direction of motion of conductor.

Index :-Direction of field

Middle :-Direction of current

What is similarity between Fleming left hand rule and fleming Right hand rule

There is a relation between the magnetic field, the current and the force in both Fleming’s left and right hand rules.

This relation is directionally determined by Fleming’s Left Hand rule and Fleming’s Right Hand rule respectively.


What it determine

These rules do not determine the magnitude but instead show the direction of any of the three parameters (magnetic field, current, force) when the direction of the other two parameters is known.


This rule Applicable for

Fleming’s Right-Hand rule is mainly applicable to electric generators.
