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. Prove that the magnetic field near the sheet is parallel to the sheet and perpendicular to the current direction, with magnitude:
[tex]
B = \frac{\mu_{0} J_{s}}{2}
[/tex]
To solve this, I know that Ampere's law should be used. It's intuitive from the right-hand rule that the direction of the magnetic field will be parallel to the sheet at points near the sheet. I'm at a loss in terms of how I can go about proving this derivation, though.
