Draw the magnetic field lines of the field produced by a current carrying circular loop. Explain with reason whether the field will be stronger at a point at the center of loop or near the circumference of loop.

Solution

As evident from the figure, the magnetic field lines will be less denser in the region near the circumference of the loop than at the center. Thus, the magnetic field will be stronger at the center of the loop than in the region near the circumference.
