Outline Reports from working groups Magnetization sheets flow compare: ? Magnetization solenoids flux compare: ΦP Magnetization currents Jb, Kb compare: ρb, σb Magnetic Intensity H B = μ0 (H+M) Geometric interpretation Boundary conditions

Working groups Develop the geometry of magnetization meshes Compare and contrast to: electric polarization chains Comparison and contrast magnetization current Jf vs Jb Relation to magnetic/magnetization surfaces of H and M Compare and contrast to: electric polarization ρf vs ρb Derivation of bound potential Compare and contrast to: electric bound potential Reconcile results with Working Group #1 Boundary value problem #1 Sphere of constant magnetization M use magnetic pole density σM Boundary value problem #2 use bound current density Kb
