Title: Apparatus for retrieving metal objects from a wellbore

Abstract: A tool for retrieving metal objects from a wellbore has a plurality of magnet assemblies spaced longitudinally along a tool body. Each magnet assembly has a plurality of magnet members, which can be arcuate or longitudinal, covering a majority surface area of the tool body. In the embodiment of the invention having longitudinal members, magnet protectors are secured immediately adjacent to a corresponding magnet member for deflecting striking force of the metal particles being attracted to the magnet during rotation of the tool. A trap space if formed between the magnet and an adjacent magnet protector for retaining more metal particles within the magnet assemblies.
