This work present two methods for designing simple and compact planar coils. The length of a constant wire width is minimized using Euclidian and Manhattan distance. Euclidian coils exhibit smooth patterns of slightly lower resistance than that of square-shape coils obtained using Manhattan distance. Manhattan coils show straight conductors which minimizes the force and facilitate the coil manufacturing. The coil sensitivity increases up to 1.8 times when placed in the iron poles but in detriment of the coil slew rate. Compact transverse coils architected using both distance minimization induces a residual eddy current smaller than 0.05% within the DSV.
