The utility model discloses a suspected stimulator for confirming the effectiveness of a magnetic stimulation therapy, which can lead a testee to feel the using feeling of a magnetic stimulator and can easily confirm the effectiveness of a practical magnetic stimulator. In order to implement the suspected stimulator, the suspected stimulator for confirming the effectiveness of the magnetic stimulation therapy comprises a main body part providing appearance, a power supplying part arranged on the main body and supplying power externally, a sound generation part arranged on the main body and generating sound, and a vibration generator arranged on the main body and generating vibration. According to the suspected magnetic stimulator, the testee can not distinguish practical implementation or processed implementation, thus eliminating psychical elements on clinical tests. The effectiveness of the magnetic stimulation therapy can be easily judged through the clinical tests of comparing the practical magnetic stimulator capable of generating a magnetic field with the suspected magnetic stimulator incapable of generating a magnetic field. A newly developed magnetic field stimulator and the suspected magnetic stimulator are utilized to easily compare the effectiveness of the newly developed magnetic field stimulator.
