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

摘要

The present invention relates to a soft magnetic thin sheet for a magnetic core which is divided into small pieces. The soft magnetic thin sheet for a magnetic core has an inductance preferential area having a first average crack gap and an eddy current suppression preferential area having a second average crack gap, wherein the average crack gaps are different. According to the present invention, eddy current loss is reduced and high inductance is maintained.
