    Sir but in FLH rule middle finger represents current direction naa then how come velocity direction is taken??pls respond

    • @s.kumarphysicsclasses
      @s.kumarphysicsclasses 19 днів тому

      This rule is used to determine the direction of force acting on: (i) a charged particle moving perpendicular to a magnetic field (ii) a current carrying conductor held perpendicular to a magnetic field. If we stretch the first finger, central finger and the thumb of our left hand mutually perpendicular to each other such that the first finger is in the direction of magnetic field, central finger is in the direction of velocity of positive charged particle (or electric current flowing in a conductor) then the thumb will represent the direction of force acting on the particle (or conductor).
