This paper presents an experimental method and theoretical analysis to study the dielectric effect in Mn-Zn ferrite cores. Experimental results show that dielectric effect becomes very pronounced at high frequency. This is caused by the high permittivity of the ferrite core. Theoretical analysis is then introduced to study the influence of high permittivity on the permeability measurement. Numerical results show that significant aberrations of measured permeability from its intrinsic value could occur due to the high permittivity in the Mn-Zn ferrite cores.
