N2 - The effect of compacting behavior of powders on the initial permeability was investigated for iron powder dust cores made from reduced iron powder and water atomized one. The initial permeability of the reduced iron powder dust core was higher than that of the water atomized one. The analysis of the compacting behavior revealed that the reduced iron powder particles were deformed more than the water atomized ones, and stretched paralell to the direction of the magnetic flux. It was indicated that the stretched shape of particles lowered an effective demagnetizing factor of the reduced iron powder dust cores, and as a result, the initial permeability was improved.
