An infinite sheet of current, perpendicular to the y axis is located at y=0. The linear current density [tex] \lambda_+_x [/tex] flows in the +x direction. By inspection, we expect the magnetic field direction B_y, on the positive y side of the sheet to be in the +z direction while the magnetic field on the negative y side of the sheet to be in the -z direction. We choose the Amperican loop as the dashed line with sides of length L and w. The magneto motive force is given by 2LB and the current enclosed is [tex] \lambda_+_x * L [/tex].(adsbygoogle = window.adsbygoogle || []).push({});

Let L=0.5 m, w=0.078 m, [tex] \lambda_+_x [/tex]= 1.89 A/m. Find the magnitude of the magnetic field B. Answer in units of T.

I really have no idea how to do this problem. Can someone help? Thanks
