Abstract: Iron cores are important units of electromagnetic devices but lack the ability to be shaped into three-dimensional objects. Soft magnetic moldable composites (SM2C) are new materials that can possibly substitute iron cores because of their malleability. The aim of this study was to explore the physical and chemical properties of SM2Cs to determine their range of applications. The thermal conductivity of SM2Cs was measured using the transient plane source (TPS) method. Results showed that the SM2Cs were not as thermally conductive as soft magnetic materials (SMM) but they have the potential to establish good thermal conductivity with coils, and because of their flexibility, can be integrated with flanges during cooling to enhance their thermal properties.
