This paper considers the effects of conductor geometry on the performance of small solenoidal coils for
high-field NMR. First, a simple analytical model is presented for investigating the effects of conductor
geometry on the current distribution in such coils. The model was used to derive optimum parameters
for coils constructed from wire with either rectangular or circular cross-sections as a function of the
length-to-diameter ratio. Second, a commercial software package utilizing full three-dimensional finite-
element solutions to Maxwell's equations was used to confirm the basic findings of the simple analytical
