Abstract
The purpose of this study is to manufacture magnetic Japanese lacquer wood which has a high relative permeability at high frequencies. The author utilized Japanese lacquer (Urushi:lacquer sap obtained from Rhus verniciflua) which has electrical insulation properties and is suitable adhesives.
The relative permeability and loss coefficient of four types of magnetic powder, mixed with different ratios of lacquer and magnetic powder were examined in this study. Measurements showed that a molybdenum permalloy based magnetic wood has the highest relative permeability.
