Abstract

In this study, a measuring system of the initial permeability of soft-ferrite powder was developed by using a differential transformer coil. and was investigated demagnetizing factors. Magnetic powder is extensively used for a magnetic fluid and microwave absorber materials etc. In these applications, it is very important for us to measure the initial permeability of magnetic ceramic powder. Unfortunately there are not any measuring equipment and method directly up to the present.
