Abstract
A Stud Finder includes a one-piece magnet assembly molded from a moldable plastic material containing a dopant capable of being permanently magnetized along a desired axis. The one-piece magnet assembly includes integral pivot bosses for pivotably supporting the magnet assembly in a location where it can be influenced by the nearby presence of magnetic metals such as steel nails. The plastic material is capable of accepting integral coloring.
