| Abstract: | Aiming at the magnetic field shielding effectiveness in magnetic fuze application, the spheroidal shell is brought forward to act as the fuze body approximate model. The magnetic shielding effectiveness of the spheroidal shell immersed in a uniform magnetic field is analyzed theoretically and the shielding coefficient expressions are induced. Moreover the correctness of the theoretical analysis is validated by experimentation. This research is of significance for the selection of magnetic fuze body's material, configuration design and the measured magnetic signal process. |
