MediumMeena draws magnetic field lines of a 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?
(N/A) The strength of the magnetic field decreases as the distance from the centre of the current-carrying loop increases.
This decrease in the strength of the magnetic field is represented by the increasing divergence (or decreasing degree of closeness) of the magnetic field lines as one moves away from the axis.
