B = 0.009 T

Explanation:

The magnetic force is given by

F = q vx B = i L x B

Bold quantities refer to vectors.

We are given some data the current (i 14.7 A), the force per unit length (F/L = 0.125 N / m)

We can take off in magnetic field since the current and the field are perpendicular, so the sine 90 = 1, write the magnitude of the equation

F = i L B

B = (F / L) 1 / i

B = 0.125 1/14.7

B = 0.009 T
