FLEMING`S LEFT HAND RULE
This rule is used for finding the direction of rotation of the armature in a DC motor.
EXPLANATION :
If we spread out the thumb, forefinger & middle finger of our right hand mutually at right angles to each other thumb indicates direction of force, forefinger indicates magnetic field, middle finger indicates direction of current.
FLEMING`S RIGHT HAND RULE
This rule is used for finding the direction of current in the conductor of a generator.
EXPLANATION :
If we spread out the thumb, forefinger & middle finger of our right hand mutually at right angles to each other the thumb is placed in the direction of motion of the conductors & the forefinger in the direction of magnetic flux then the middle finger gives the induced emf direction.
