Abstract: The measuring principle of the magnetoelectric effect by dynamic method is described, and the corresponding measuring device is optimized to design and set up. The effect of some important parameters on the measuring results is investigated. It are shown that the choice of the suitable parameters is important for the measuring results and the actual reqiurement must be meeted during the design of the measuring device. It is advantageous for the improvement of the measuring precision and reduction of the measuring errors to enlarge the length of the coil,decrease the number of turns of the coil,and reduce the strength of the AC magnetic field.
