The paper reviews the development of two branches of analysis tools, i.e., magnetic circuits and field solvers, and their implementation with an industrial design process for low frequency electromagnetic devices. The current state of the art is described along with the rationale for the current research work being carried out. The slow uptake of advanced analysis tools by industrial designers is examined and reasons given. The impact of manufacturing processes on the structure of design tools is considered. A development roadmap is developed with the goal of creating advanced industrial tools which will reduce the need for physical prototypes and thus reduce the overall cost of electromagnetic devices both in design and manufacture.
