Unformatted text preview: such a way that J is proportional to s , the distance from the axis. 8. (Griffiths 5.14) A thick slab extending from z= -a to z =+a carries a uniform volume current J = J x-direction. Find the magnetic field as a function of z, both inside and outside the slab. 9. Challenge Problem (you do not have to hand this in). (Griffiths 5.20) Show that Ampere’s law is NOT consistent with the general rule that the divergence of a curl is always zero? When does it break down? How can one “fix” it?...
