The invention relates to a method for detecting a static frequency scanning for a coin magnetoelectricity characteristic parameter and a corresponding detector, which belongs to a technical field for coin fake evaluation. The method comprises the following steps: loading a frequency scanning electrical signal which changes in the predefined frequency range to a detecting winding; placing the detected coin on one side of the detecting winding to allow the winding to generate vortex and form an invert magnetic field; recording a group of viewed impedance variety data of the detecting winding; performing data processing for the measured viewed impedance variety data; taking the result of data processing as the characteristic data of the detected coin, and comparing with the corresponding demarcated characteristic data of serial standard coin so as to get the detecting result. The corresponding detector comprises a frequency scanning signal generator, the detecting winding and a microprocessor. The frequency scanning method adopted by the invention is different from the prior art and can detect the changes of magnet conductive rate and average electricity conductive rate of coin in continuous frequency band so as to determine the magnetoelectricity characteristic parameters of various coins in wide frequency, thus achieving the anti-fake design and detection of reading the magnetoelectricity characteristic of coin machine.
