A thin infinitely large current sheet lies in the y-z plane.Current of magnitude J_s per unit length along the z axis travels in the y-axis direction,which is up out of the page.Which diagram below correctly represents the direction of the magnetic field on either side of the sheet?

According to the right-hand rule, if current flows in the positive z-direction (out of the page) and in the y-direction (up), then the magnetic field will be in the negative x-direction. On one side of the sheet, the magnetic field will be in the negative x-direction (towards the left) and on the other side, it will be in the positive x-direction (towards the right). Option D correctly represents this scenario.
