Magnetic structures, magnetic domains and topological magnetic textures of magnetic materials
Acta Physica Sinica, 2015 This article first gives a brief review of magnetic structures, magnetic domains and topological magnetic textures and their relations. On the one hand, the magnetic domains are determined by the magnetic structures, the intrinsic magnetic properties and the micro-structural factors of a material.

Physical Modeling of Core Losses in Ferrite E-Cores
IEEE Open Journal of Power ElectronicsThe development of advanced power electronic converters requires an accurate calculation of core losses in magnetic devices. But the losses in the widely used ferrite cores depend on the shape of the core, especially above 10 kHz, meaning that core ...

Intestinal fistula after magnets ingestion
Einstein (São Paulo)Accidental ingestion of magnetic foreign bodies has become more common due to increased availability of objects and toys with magnetic elements. The majority of them traverse the gastrointestinal system spontaneously without complication.

Unbalanced-Flux Concept for High Power Density Magnetics and Review of the MHz LLC Transformers
IEEE Open Journal of the Industrial Electronics SocietyHigh-power-density magnetics are often designed through the MHz-frequency approach, but this method is constrained by excessive core losses, which restrict operation to very low magnetic flux density B, typically lower than 70 mT.
