Abstract Background The aim of this study was to investigate in vivo the quality of bone healing under the effect of a static magnetic field arranged inside the body. Methods A metallic device was developed consisting of two stainless steel washers attached to the bone structure with titanium screws. Twenty-one Wistar rats Rattus novergicus albinus were used in this randomized experimental study. Each experimental group had five rats and two animals were included as control for each of the groups. A pair of metal device was attached to the left femur of each animal lightly touching a surgically created bone cavity. In the experimental groups washers were placed in that way that they allowed mutual attraction forces. In the control group surgery was performed but washers screws or instruments .
