Magnetic Induction of Spherical and Prolate Spheroidal Bodies with Infinitesimally Thin Current Bands Having a Common Axis of Symmetry and in a Uniform Inducing Field. A Summary

Modeling and Characterization of a ReBCO HTS Degaussing Demonstrator

“…The magnetic field around a spherical ferromagnetic shell in a constant background field can be described using a series of equations as described by Baker and Brown [12]. The magnetic field around a spherical shell with current bands outside or inside the shell can be described by solving the Laplace equation for the vector potential A [12].…”

“…The magnetic field around a spherical ferromagnetic shell in a constant background field can be described using a series of equations as described by Baker and Brown [12]. The magnetic field around a spherical shell with current bands outside or inside the shell can be described by solving the Laplace equation for the vector potential A [12]. Because of the superposition principle, the solution for a spherical shell with a constant background field and the solution for a spherical shell with a current band inside or outside of it can be combined into a new solution.…”

Application of Models in the Design of Underwater Electromagnetic Signature Reduction Systems

“…For example, the vertical magnetic field signatures analytically computed (Baker and Brown 1982) and experimentally measured on a solid ellipsoid are compared in Figure 1. An 18,000 nT uniform magnetic field was applied to the longitudinal axis of the ellipsoid, which has a permeability constant of 80 and a major and minor axis length of 1.5 and 0.15 m, respectively.…”
