According to the principle of "Uniform magnetization" the 2-dimensional space expression for the constant direction magnetized multi-piece ring structure with plane head is given by the method of harmonic analysis. The imaginary project of 16-piece plane head quadrupole is computed
and comparison has been made with selected ordinary electromagnetic lens system.
