Verified by ExpertsA
The loop mentioned in the question must look like one as shown in the figure.
Magnetic field at the center due to semicircular loop lying in x-y plane,
negative z direction
Similarly field due to loop in x–z plane, Bxz = 
in negative y direction.
∴ Magnitude of resultant magnetic field,
B = 
=
