Fleming’s Left Hand rule:
If we hold the forefinger,center finger and thumb of our left hand at right angles to one another.Let us adjust the hand in such a way that our center finger points towards west and thumb points towards north.We see that, our forefinger will be pointing upward.This is the direction of magnetic field.
