5) The figure below illustrates a large, flat, metal rectangular plate having large length, L (measured along the x-axis), large width, W (measured along the y-axis), and small thickness T (measured along the z-axis). Current I flows through the plate with uniform current density (directed along the positive x-axis) a) Use a symmetry argument to determine the direction of the magnetic field near the center of the plate at a field point, which is a distance z above the geometric...
