Abstract The analysis method used in the previous paper by the authors is extended to the magnetic deflectors with ferromagnetic shield. The shape of the deflector winding may be arbitrary. It may be radial or non-radial, saddle, toroidal or fan-shape, etc.. A set of new expressions for the deflection field is suggested for the case where the windings are spaced by a gap from the shield. The integral equations are solved by Gauss-Chebyshev quadrature. The computation results are checked with the values measured from a deflector of CRT COTY GE-14''.
