Question

Meena draws magnetic field lines of field close to the axis of a current carrying circular loop. As she moves away from the centre of the circular loop she observes that the lines keep on diverging. How will you explain her observation?

Answer 1

It is so because the magnetic strength is strongest at pole and least in between so the lines are concentrated near poles and diverges in between.

Answer 2

Given that Meena sketches magnetic field of lines close to axis of circular loop carrying current. When "she moves away from centre of circular loop", she observes that the lines, which she had drawn keep on diverging .

This is because that the magnetic field is strong only to the axis of the current if meena moves away a distance from the loop the strength of the magnetic field decreases as the distance increases.

The main observation is the diverging of the lines occurs only if the distance of closeness from the centre of the lines increases.
