A conductor carrying 14.7 amps of current is directed along the positive x-axis and perpendicular to a uniform magnetic field. A
magnetic force per unit length of 0.125 N/m acts on the conductor in the negative y direction. What is the strength of the magnetic field at the place where the current is? 0.0013 T 0.0001 T 0.0085 T 0.0005 T What is the direction of the magnetic field? +x direction −x direction +y direction −y direction +z direction −z direction
Under the definition of force on a magnetic field we proceed to make the point a,
A)
Since the field is perpendicular, then \theta = 0
b) The direction of the magnetic field would be done in + Zdirection. This when understanding that the vector extends along the z + axis of the formula
