The purpose of this paper is to propose a method for measuring the permeability of a magnetic fluid with a ferrite core, with a gap, where the core is excited and placed within the magnetic fluid. Several different materials and sizes are examined. Comparative experiments with the ring core method show that the proposed method is more effective for measuring ac permeability.
