A magnetic leveling device for measuring inclinations of a ferromagnetic surface comprising:
- a level frame including a 1st flat surface, the 1st flat surface being configured to rest against the ferromagnetic surface, the 1st flat surface defining a 1st surface inclination;
- a horizontal bubble tube fixed to the level frame and configured to indicate when the 1st surface inclination is horizontal;
- a vertical bubble tube fixed to the level frame and configured to indicate when the 1st surface inclination is vertical;
- a 45-degree bubble tube fixed to the level frame and configured to indicate when the 1st surface inclination is 45 degrees;
- a 30-degree bubble tube fixed to the level frame and configured to indicate when the 1st surface inclination is 30 degrees;
- and
- a 1st flat-surface magnet set is embedded within the level frame, flush with the 1st flat surface,
- wherein the level frame is a cuboid and further includes a 2nd flat surface, a 3rd flat surface, a 4th flat surface, a 1st face, and a 2nd face, each configured to rest against the ferromagnetic surface, the 1st face and the 2nd face defining opposite sides of the cuboid and the 1st, 2nd, 3rd, and 4th flat surfaces defining a rectangular perimeter about the cuboid between the 1st and the 2nd faces,
- further comprising:
- a 2nd flat-surface magnet set disposed flush with the 2nd flat surface and configured to magnetically couple the ferromagnetic surface to the 2nd flat surface;
- a 3rd flat-surface magnet set disposed flush with the 3rd flat surface and configured to magnetically couple the ferromagnetic surface to the 3rd flat surface;
- a 4th flat-surface magnet set disposed flush with the 4th flat surface and configured to magnetically couple the ferromagnetic surface to the 4th flat surface;
- and
- a face magnet set disposed flush with the 1st face and configured to magnetically couple the ferromagnetic surface to the 1st face,
- wherein the cuboid is substantially solid, and the level frame further includes a plurality of apertures extending through and between the 1st face and the 2nd face;
- wherein each of the horizontal bubble tube, the vertical bubble tube, the 45-degree bubble tube, and the 30-degree bubble tube are positioned within one of the plurality of apertures;
- wherein each of the horizontal bubble tube, the vertical bubble tube, the 45-degree bubble tube, and the 30-degree bubble tube are recessed between or flush with the 3rd flat surface and the 4th flat surface;
- wherein some of the plurality of apertures are cylindrical and have a ¾-inch diameter;
- wherein the cuboid has a 9-inch length measured between the 4th flat surface and the 3rd flat surface;
- wherein the cuboid has a 1⅝-inch height measured between the 2nd flat surface and the 1st flat surface;
- wherein the cuboid has a 1⅝-inch thickness measured between the 1st face and the 2nd face;
- and
- wherein the magnets of the 1st flat-surface-magnet set, the 2nd flat-surface-magnet set, the 3rd flat-surface-magnet set, the 4th flat-surface magnet set, and the face magnet set are all cylindrical and have a ¼-inch diameter.
