Two solid, infinitely-long, circular cylinders are placed parallel to the z axis. one cylinder has radius ai, has its axis at (x, y)=(-d, 0), and carries a uniform electric current density j1 in the positive z direction. the other cylinder has radius d2, has its axis at (x, y) -(d, 0), and carries a uniform electric current density j2 in the positive z direction, note that ^ = tatya -yi+x (1) find the b field everywhere outside the cylinders in terms of rectangular coordinates (2) find what this b field reduces down to on the y-z plane. (3) suppose we want the b field on the y-z plane to only have an x component. if a, as and j are fixed, what value of should we use to make this happen? (4) suppose we want the b field on the y-z plane to only have a y component. if ai, as, and j are fixed, what value of should we use to make this happen?
