(b) distance of the conductor from the point
(c) length of the conductor
(d) none

Answer 1

Answer:

This conclusion is independent of the relative positions of current ... Magnetic field due current in finite straight wire Magnitude of magnetic field ..... Magnetic field due to current in infinite (long) straight wire.

Answer 2

Answer:

Opt c

Explanation :
length of the conductor
