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 \( \mathrm{r} \) and \( 2 \mathrm{r} \). Each segment of arc subtends equal angle at the common centre \( P \). The magnetic field produced by current path at point \( \mathrm{P} \) is
