In a large homogeneous material slab with conductivity flows a homogeneous current in one direction. A cylindrical hole is drilled through the slab with radius .
(a) Find the changed current density in the slab outside the hole.
(b) What scalar quantity is reasonable to graph here besides the vector field representing the current flow? Make a graph of this scalar quantity.
