The number of turns is N = s/d = 5/.0216 = 231. Therefore, N x I = 115.5 Ampere-turns. Since no ferromagnetic
materials are present, the field due to induced magnetization, Hm = 0, and thus no scalar potential is required.
The total field can be determined from the numerical integration of the coil source field upon specification of
the coil with the current source element (SOURC36). Since the field is symmetric, an arbitrary arc of 10° is chosen
with an additional symmetry plane taken along the coil midspan....
