Core loss analysis of soft magnetic composites considering the inter-particle eddy current loss
AIP Advances, 2021 Soft magnetic composite (SMC) is composed of ferromagnetic particles surrounded by electrical insulation layer. During the manufacturing process, the electric insulation layer may be destroyed and thus the eddy current will be induced, which makes it ...

On the Eddy Current Losses in Metallic Towers [PDF]
International Journal of Renewable Energy Development, 2020 The existence of magnetic field around high-voltage overhead transmission lines or low-voltage distribution lines is a known fact and well-studied in the literature. However, the interaction of this magnetic field either with transmission or distribution towers has not been investigated. Noteworthy it is to remember that this field is time-varying with
