Zusammenfassung:	The present invention relates to a magneto-rheological fluid characteristic evaluation method. According to the present invention, the magneto-rheological fluid characteristic evaluation method is a method for characterizing a magnetic rheological fluid including a dispersion medium and magnetic particles. The magneto-rheological fluid characteristic evaluation method comprises the steps of: (a) preparing a container filled with a magneto-rheological fluid or a flow path through which the magneto-rheological fluid flows; (b) positioning a coil portion such that the container or the flow path is located in a hollow region of the coil portion; and (c) measuring an impedance signal or an inductance signal for the magneto-rheological fluid through the coil portion. 본 발명은 자기유변유체의 특성 평가 방법에 관한 것이다. 본 발명에 따른 자기유변유체의 특성 평가 방법은 분산매체 및 자성입자를 포함하는 포함하는 자기유변유체(Magnetic Rheological Fluid)의 특성 평가 방법으로서, (a) 자기유변유체가 채워진 용기 또는 자기유변유체가 흐르는 유로를 준비하는 단계; (b) 코일부의 중공 영역에 상기 용기 또는 상기 유로가 위치하도록 상기 코일부를 배치하는 단계; 및 (c) 상기 코일부를 통해 상기 자기유변유체에 대한 임피던스 신호 또는 인덕턴스 신호를 측정하는 단계;를 포함하는 것을 특징으로 한다.
