Question

as we move away from current carrying conductor the spacing between magnetic field lines of force

Answer 1

Answer :- $\underline{\bold{increases}}$

Magnetic lines of force is directly proportional to magnetic field intensity .
Higher density of magnetic lines of force , higher will be magnetic field intensity.
But we know, magnetic field intensity is inversely proportional to square of speration between given conductor to observation point.
e.g., $\bold{B\propto\frac{1}{r^2}}$

It means, as we move away from the current carrying conductor the spacing between magnetic lines of force increases because of this intensity or strength of magnetic field decreases .

Answer 2

Hi there.

As we move away from the current carrying conductor the spacing between the magnetic field lines of the force increases.

Explanation 

We know that the Magnetic Field Intensity is inversely proportional to the square of the separation. Also, Magnetic lines of the force is directly proportional to the Magnetic filed intensity.

Thus, Magnetic lines of force is inversely proportional to the Square of the separation.
Hence, if we move away from the current carrying conductor then the distance between the magnetic lines of the force increases.


Hope it helps.
