Developing MR based field probes requires careful
design, because a distorted local magnetic field within
the sample droplet can lead to a significant reduction
in signal fidelity. By simulating the local field
variations due to the susceptibility of the field probe
itself, we demonstrate a novel approach to acquiring
appropriate design parameters in order to optimise the
performance of new probe prototypes. We compare our
numerical results with experimental data in order to
verify and explore the capabilities of the simulation.
