Investigation has been made on the losses in magnetic cores consisting of strips of iron-nickel-cobalt alloy after annealment in a longitudinal magnetic field. It has been found that the p/f-f curve shows obvious anomalous behaviour. Explanation is given for this behaviour with a Theoretical model of the anomalous eddy current loss caused by the wall displacement in the 180?domains. Possible ways of minimizing the loss are suggested.
