WebThe variational form of the above equation is ∫ V ∇ × δA ⋅ (μ - 1 ⋅ ∇ × A)dV+ ∫ VδA ⋅ σE ⋅ ∂ A / ∂ tdV = ∫ VδA ⋅ JdV + ∫ SδA ⋅ K dS, where δA represents the variation of the magnetic vector potential, and K represents the applied tangential surface current density, if any, at the external surfaces. WebApr 18, 2010 · Theory. Fundamental electromagnetism equations and theory are drawn from Griffiths, while the theory of induction heating is drawn from the Induction Heating Handbook (Davies and Simpson) chapter 12 and Conduction and Induction Heating (E.J. Davies). Research on hysteresis was drawn from Hysteresis in Magnetism (Bertotti).
