ABSTRACT:
A hand held magnetic pickup which meets both the requirements of being able to remove magnetic debris from a narrow channel or gap, and of being sufficiently strong to pick up all magnetic debris over a wide area. The invention is an elongate, rare earth magnet in the form of a rod or bar having a narrow cross section, embedded in a wooden or other non magnetic handle. The length of the magnet is greater than twice the length of the handle, so that the overall magnet has a high length to cross section ratio.
