Question

Name three factors on which the magnitude of force on a current carrying conductor placed in a magnetic field depends and state how does the force depend on the factors stated by you.

Answer 1

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:

1. The force F is directly proportional to the strength of magnetic field B, i.e., F α B
2. The force F is directly proportional to the current I flowing in the wire, i.e., F α I
3. The force F is directly proportional to the length L of the wire (within the magnetic field) i.e., F α L
