Abstract:
1. A level for indicating the orientation of a surface, the level comprising: a first planar surface; a second planar surface; a web coupled to the first planar surface and the second planar surface such that the first planar surface is spaced apart from and is parallel to the second planar surface; a vial having a long axis and containing a liquid and a gas bubble, the vial coupled to the web; a first magnet coupled to the first planar surface; a second magnet coupled to the first planar surface and spaced apart from the first magnet by a first distance; and a third magnet coupled to the first planar surface and spaced apart from the second magnet by a second distance that is different than the first distance; wherein the first, second, and third magnets are positioned along the first planar surface successively without any additional magnets positioned therebetween.
