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 ? (CBSE 2010)
Solution:
Magnetic field due to current carrying circular loop decreases as we move away from the centre of the loop. Diverging field lines represent weak
magnetic field.
