Answer:
0.0085 T
Explanation:
The magnetic force per unit length exerted on a current-carrying wire is given by

where
B is the strength of the magnetic field
I is the current
is the angle between the directions of B and I
In this problem, we know

I = 14.7 A (the current)
since I and B are perpendicular
Therefore, solving for B, we find the strength of the field:
