Improved permeability of Fe based amorphous magnetic powder cores by adding Permalloy

•Addition micro size Permalloy into non-magnetic gap can improve the permeability.•A certain content of Permalloy can maximize permeability and reduce core loss.•There is an optimal range of coating content to increase the permeability.•The permeability of the cores increases by 59.6% and core loss...

This paper focuses on improving the permeability of Fe-Si-B based amorphous magnetic powder cores by addition of micron-sized ferromagnetic crystalline metal particles (Permalloy). The effects of Permalloy content, size and the amount of insulation on magnetic properties and density were investigated.
