  State factors on which force acting on a current-carrying conductor in a magnetic field depends. Hence, obtain the formula to find the force.

Answer:

                  The force .F acting on a current-carrying conductor in a magnetic field depends on length of a conductor I, current I, angle  in magnetic field B.                                               (1) If F is the force acting on a conductor of length I, carrying-current l when placed at angle  in magnetic field B, then or
