This paper shows the experimental results for the measurements of complex magnetic permea-bility of ring-shaped magnetic woods as a function of frequency between 1 MHz and 1.8 GHz. Comparison of complex permeabilities between magnetic fluid and magnetic powder are also shown. The results show that the complex permeability of magnetic wooden materials using magnetic powder is higher than that of the wood impregnated with a magnetic fluid at high frequency. In both cases, the imaginary components of complex permeability increase with frequency.
