Re: [Phys-L] amusing electrostatics exercise

[Bruce Sherwood <Bruce_Sherwood@ncsu.edu>]

One way to handle this is to consider the superposition of the field of a
solid wire and the field of a wire the size of the hole, with current
running in the opposite direction. Ampere's law gives you the field at any
location for each of these current distributions; add them vectorially.
