Yn. Grigorev et al., ABOUT ACCURACY OF MEASUREMENTS OF FRINGING MAGNETIC-FIELD CHARACTERISTICS, IEEE transactions on magnetics, 30(4), 1994, pp. 2640-2642
Coefficients of Taylor series expansion up to the fourth order are rep
orted for three projections of the fringing magnetic field. Computer s
imulation is used to investigate the problem of accuracy of measuring
multipole coefficients of the fringing magnetic field. It is demonstra
ted that the necessary accuracy of this measurements can be achieved b
y using the ''spatial field'' model to approximate the field by increa
sing the number of measuring points.
