Answer
(a) Experimentally, it is found that the magnitude of force acting on a current carrying conductor placed in a magnetic field in the direction perpendicular to it's length, depends on the following factors —
- The force F is directly proportional to the strength of magnetic field B, i.e., F α B
- The force F is directly proportional to the current I flowing in the wire, i.e., F α I
(b) Fleming's left hand rule.
