Magnetic Field Due to Circular Current Carrying Wire: Practice Problem & Solution

A current I flows around a closed path in the horizontal plane of the circle as shown in the figure. The path consists of eight arcs with alternating radii r and 2r. Each segment of arc subtends equal angle at the common centre P. The magnetic field produced by current path at point P is Magnetic Field Due to Circular Current Carrying Wire diagram: A current I flows around a closed path
