A device for magnetic stimulation of body regions, including at least one magnetic coil connected to a stimulator which has a power element for generating electrical impulses to be applied to the at least one magnetic coil, so that the generated magnetic field can be induced in the body region, wherein a detection unit is provided for detecting metal elements within the body region. A measuring device is provided for detecting the electrical power received by the magnetic coil and a comparison device is provided for comparing the power with a predetermined limit value, the detection unit is connected to the stimulator, and the comparison unit is designed to automatically switch off the stimulator or reduce the power of the stimulator or of the power element of the stimulator in the event of the predetermined limit value being exceeded.
