Magnetic field due to currentHard
Question
A current I flows a closed path in the horizontal plane of the circle as shown in the figure. The path consists of eight wires 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
