The determination of the fleld parameters of saddle deflection yoke with a ferromagnetic shield

Abstract

The analysis and computation of the field distribution of the saddle deflection coil with a ferromagnetic shield by the boundary element method are described, and the limitations of the model proposed by D. M. Fye (1979) is pointed out. The Green's function is expanded by the Maclaurin series, and the analytical forms of the field parametersB ₀, B₂, andB ₄ are given. The results obtained agree well with the experimentally measured values.
