<p>Over the past ten to fifteen years the area of Nuclear Magnetic Resonance (NMR)
Spectroscopy has seen tremendous growth. For example, in conjunction with multiple
quantum NMR, molecular structural mapping of a compound can be easily performed in a
two dimensional (2D) experiment.</p>
However, only two kinds of detector coils have been typically used in NMR studies.
These are the solenoid coil and the Helmholtz coil. The solenoid coil was very popular with
the permanent and electromagnet NMR instruments. With the advent of the superconducting
magnets the popularity shifted to the Helmholtz coil, which remains the most common coil
