text: a research paper on magnets and if a magnet is stronger on its ends or in the middle?   a magnet has a stronger field in the middle. the field lines can only be observed as they separate at the ends, and where the density of field lines in decreasing. the field strength at a given distance measured perpendicular to the axis of the magnet is always greater in the region opposite the middle than opposite the ends. this is the case for all fields that vary as the inverse square from point sources, magnetic, electric, and electromagnetic (from radioactive sources or light).
