Magnetic field due to straight current carrying wires

A wire consists of two semi-infinite line segments along the vertical and horizontal axes, and a half-square section of side length $1 m$ , as shown in the image.

The wire carries a uniform current of $10 A$ .

Determine the magnitude of the magnetic flux density $(B)$ , at the origin.

Details and Assumptions:
- The magnetic permeability $\mu_0 = 4 \pi \times 10^{-7} H/m$
- Give your answer in $\mu T$ , to 3 decimal places. Here, the symbol $\mu$ denotes "micro".
