ON THE ANALYSIS OF MAGNETIC MULTIPOLE FIELD WITH FIXED DIRECTION MAGNETIZED MULTI-SEGMENTED RING STRUCTURE

According to the principle of the "uniform magnetization" and harmonic analytic method, the fields of the ring structure system with multi-segmented and trapezoidal magnet are analysed. The 3-dimensional expression of the field at any point of the space is given, and the 2-dimensional expression of the fundamental component of multipole, harmonic and leakage field is also given.The comparisons between the property of segmental and trapezoidal magnet are discussed.
