Perfectly conducting electrodes are composed of sheets bent into the shape 
shown in Fig. P8.6.5. The length of the system in the z direction is very large compared to the length 2a or height d, so the fields can be regarded as two dimensional. The insulating gaps have a width 
that is small compared to all dimensions. Passing through these gaps is a magnetic flux (per unit length in the 
direction) 
. One method of solution is suggested by Example 6.6.3.
