Question
Explain with the help of the pattern of magnetic field lines the distribution of the magnetic field due to a current-carrying a circular loop.

Solution
A circular current-carrying loop creates a magnetic field that can be visualized as concentric circles around every point of the wire. As you move further from the wire, these circles expand in size. At the very center of the loop, these expanding arcs appear as straight lines. Notably, the magnetic field maintains a consistent direction everywhere inside the loop.
