The electromagnetic stimulation device contains at least a positive electrode and at least a negative electrode. An insulating gap having width of a first distance is maintained between the positive and negative electrodes. The positive and negative electrodes are at least at a second distance away from a nerve to be stimulated. A preset voltage is applied to the positive and negative electrodes so that a low-power, low-temperature, high-frequency electromagnetic field covering and stimulating the nerve is produced between the positive and negative electrodes. By the stimulation of the low-power, low-temperature, high-frequency electromagnetic field, the nerve's threshold is increased, the nerve's transmission capability is reduced, and therefore the nerve pain is effectively eased.
