An apparatus and method are provided to calculate the strength of an electromagnetic field radiated from an electric device according to a moment method, wherein the moment method is based on integral equations derived from electromagnetic equations. The apparatus and method include a setting unit to interactively set a name of a two-wire cable arranged in the electric device and coordinates of the two-wire cable at a cable inlet, a cable outlet, and way points in the electric device, the way points being prepared as and when required to bend the two-wire cable between the cable inlet and the cable outlet. Further, the apparatus and method include library unit corresponding to cable names, respectively, and storing attributes of a corresponding cable comprising of the name, type, characteristic impedance, and structural data of the two-wire cable. A generation unit is provided to generate a moment-method model of the two-wire cable according to the attributes of the two-wire cable read out of the at least one library unit specified by the name of the two-wire cable set by the setting unit and the coordinates of the two-wire cable at the cable inlet, cable outlet, and way points set by the setting unit. A calculation unit calculates the strength of the electromagnetic field radiated from the electric device according to the moment-method model of the two-wire cable and the moment method.
