19. Our approximation formula [Eq. ] was presented in Ref. 1 and was tested and compared against the circular current loop approximation found in Ref. 18, and it represents the measured experimental values of the magnet magnetic field with good accuracy. This approximation considers the nonzero second-order term in the expansion of the magnetic moment in terms of Legendre polynomials [Ref. 1, Eq. (28)].
