Step-by-step explanation:
It is given that,
Current carried in the conductor, I = 14.7 A (+x axis)
The magnetic force per unit length on the conductor,
(-y axis)
The magnetic force is given by :




B = 0.0085 T
According to right hand rule, the direction of magnetic force can be calculated. So, the direction of magnetic field is along +z axis. Hence, this is the required solution.
