The magnitude of force acting on a current carrying conductor placed in a magnetic field depends on the following factors:
(i) The force F is directly proportional to the strength of the current flowing in the conductor, i.e., F ∝ i.
(ii) The force F is directly proportional to the strength of the magnetic field, i.e., F ∝ B; and
(iii) The force F is directly proportional to the length of the conductor, i.e., F ∝ l.
