A current loop consists of two identical semicircular parts each of radius $\displaystyle R$, one lying in the $\displaystyle x-y$ plane and the other in $\displaystyle x-z$ plane. If the current in the loop is $\displaystyle i$. The resultant magnetic field due to the two semicircular parts at their common centre is
