An infinite sheet of current lying in the yz plane carries
Chapter 30, Problem 34(choose chapter or problem)
An infinite sheet of current lying in the yz plane carries a surface current of linear density Js. The current is in the positive z direction, and Js represents the current per unit length measured along the y axis. Figure P30.34 is an edge view of the sheet. Prove that the magnetic field near the sheet is parallel to the sheet and perpendicular to the current direction, with magnitude m0 Js /2.
