ABSTRACT:
A high energy magnetizer/demagnetizer on a nonoperative portion of a housing of a power driving tool includes a magnetizer/demagnetizer body on the nonoperative portion of the power driving tool and defining a mounting axis. At least one permanent magnet is formed of a magnetized material having North and South poles defining a magnetic axis and arranged on the body of the power driving tool to permit selective placement of a magnetizable element at at least one position along the magnetic axis at a predetermined distance from one of the poles to magnetize the element and placement of the magnetizable element at a selected distance from the other of the magnetic poles greater than the predetermined distance to demagnetize the element. In this way, a magnetizable element may be initially magnetized by the magnetizer on the housing of the power driving tool by positioning same adjacent to one of the poles mounted on the nonoperative portion of the driving tool and optionally subsequently demagnetized by positioning the magnetizable element a selected distance from the other of the poles.
