A device for magneto-mechanically radiating oscillating magnetic fields by periodically and precisely moving permanent magnets such that the field they continually radiate oscillates precisely. The device provides for varying magnetic field therapy as well as for use in other areas such as magnetic therapy for mammals and for improving plant growth. The device provides a varying magnetic field therapy that allows a user to use it without any change to the aesthetics of the location it is used in because the field can radiate through, or from under, objects.
