## The Attempt at a Solution

i = 5A, d=8cm, R=5cm.

Okay so we will have a two 3,4,5 triangles back to back from the center of each wire to the point in question. Since the currents are in the same direction, the magnetic field will point in the same direction and add together.

[tex]B = \frac{\mu _{0}i}{\pi R} = 40 \mu T[/tex]

The answer is given as 24uT.

What am I doing wrong?
