उत्तर
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 three 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
- The force F is directly proportional to the length L of the wire (within the magnetic field) i.e., F α L
