Question

A conductor carrying a current I = 13.8 A is directed along the positive x axis and perpendicular to a uniform magnetic field. A magnetic force per unit length of 0.116 N/m acts on the conductor in the negative y direction.
(a) Determine the magnitude of the magnetic field in the region through which the current passes.
1 T
(b) Determine the direction of the magnetic field in the region through which the current passes.
+x direction ?x direction +y direction ?y direction +z direction ?z direction

Answer 1

Answer:

a) B=0.008 T

b) +z direction

Explanation:

solution:

a) The magnetic force:

        F=i*l*B

Solve for B:  

      B=0.008 T

b) According to the left hand rule, the magnetic field is in the +z direction
