This can be analyzed with the ferromagnetic material and the air in the cavity as a parallel magnetic circuit; because the magnetic conductivity of the ferromagnetic material is thousands of times greater than that of air, the magnetic resistance of the cavity is much greater than that of the ferromagnetic material, most of the magnetic induction lines of the external magnetic field pass through the wall of the ferromagnetic material, and the magnetic flux entering the cavity is extremely small; thus, the cavity shielded by the ferromagnetic material is basically free of an external magnetic field, thereby achieving the purpose of magnetostatic shielding; the higher the magnetic conductivity of the material is, the thicker the cylinder wall is, the more remarkable the shielding effect is. Because the shielding layer is made of ferromagnetic materials with high magnetic conductivity, such as soft iron, silicon steel and permalloy, the magnetostatic shielding is called ferromagnetic shielding; whenever possible, the shield should be close to all walls to avoid magnetic field leakage, this structure being most nearly circular even if rectangular, which can create a semi-closed magnetic circuit;
