Device for stimulation of the nervous system by means of magnetic fields comprising: A rigid helmet (1) defining a concave interior engageable with at least a portion of a user's head loosely, and a convex exterior； At least one support (21) for a magnet (10), said support (21) being fixed to said helmet (1) for the application of a magnetic field on the user's head； Movement means (20) for regulating the distance between said at least one support (21) and the user's head； Characterized because The displacement means (20) move in a guided manner the aforementioned support (21) carrying said magnet (10), which is at least one, causing said magnet (10) to protrude from the concave interior of the helmet (1) until reaching a stimulation position in which the magnet (10) or its corresponding support (21) comes into contact with the user's head； and because The displacement means (20), together with said at least one support (21), fix said rigid helmet (1) on heads of different size and shape of different users by means of a different regulation of the position of said at least one support (21) to eliminate the gap between the concave interior of the helmet (1) and the head.
