Magnetic Field Analysis Using Magnetic Charge Equivalent to Electric Current in Arbitrary Symmetric Windings

For a symmetric winding with homogeneous volume current density, the current density can be transformed to equivalent magnetic charge by superposing layers of sheet currents to represent volume current density. In the transformation process, equivalent permanent magnetization needs to be found. Yet, the equation for equivalent permanent magnetization was presented only for rectangular coils. This paper proposes a generalized equation for equivalent permanent magnetization to find magnetic charge equivalent to electric current in an arbitrary symmetric winding.
