Spatial Distribution of Magnetic Field under Spherical Shell Plasma

Magnetic field intensity is modeled using Laplacian equations to study the spatial distribution of magnetic field under spherical shell plasma. The influences of different internal and external radii are also considered. In addition, the magnetic field calculation of plasma space is analyzed. The main conclusions are as follows. The external uniform magnetic field H-0 is the scalar magnetic bit, and the magnetic charge of the shell of the plasma is equivalent to that of a magnetic dipole. The magnetic field in the spherical shell is a superposition of a uniform field and a magnetic dipole field. The uniform field is composed of an externally applied uniform field H-0 and a uniform field generated by the magnetic charge on the outer surface of the ball. The magnetic dipole field is generated by the magnetic charge on the inner surface of the shell, and the inside of the shell is a uniform magnetic field. When mu(2)/mu(1) is high and a/b is low, the ratio of the magnetic field strength H-3 (the region is r < a) to the magnetic field strength H-0 (the region is r > b) is low. By contrast, when mu(2)/mu(1) and a/b are high, the ratio of the magnetic field strength H-3 to the magnetic field strength Ho is high. When the magnetic permeability of the inner object is small and the spherical shell is thick, the produced plasma sheath is thick, and the external magnetic field in the spherical shell is weak. Therefore, when the shielding effect is good, the possibility that the "black barrier" phenomenon will occur is high, and ground radar detection will be difficult.
