SOFT MAGNETIC THIN RIBBON FOR MAGNETIC CORE, MAGNETIC CORE, COIL UNIT, AND WIRELESS POWER TRANSMISSION UNIT

摘要

PROBLEM TO BE SOLVED: To provide a soft magnetic thin ribbon for a magnetic core in which reduction in eddy current loss and maintenance of high inductance are compatible.SOLUTION: A soft magnetic thin ribbon 10 for a magnetic core according to the present invention, which is divided into small pieces, includes an inductance priority region 1a having a first average crack interval in which average crack intervals are different from each other and an eddy current suppressing priority region 1b having a second average crack interval.SELECTED DRAWING: Figure 1
