Infinitely many long, straight conductors with square cross sections are laid side-by-side to form an infinitely large sheet of current. Each conductor carries a current I that is distributed uniformly over the cross section of the conductor. The conductors lie in the xy-plane, are parallel to the y-axis, and carry current in the +y-direction. There are n conductors per unit length measured along the x-axis. ● ● I X y z (a) The magnetic field above the current sheet points in the -x-direction, and the field below the sheet points in the +x-direction. Argue why this must be true based on the symmetry of the current distribution. (b) Use Ampere's law to find the magnitude of the magnetic field a distance a above the current sheet. (Hint: Your Amperian loop should be rectangular and enclose some current. At a given point on the Amperian loop, the magnetic field should be either parallel or perpendicular to the integration path.)
