Abstract 1. In a magnetometer, an open-ended cylindrical tube composed of a non-magnetic material and having an opening in the longitudinal sidewall thereof substantially closer to one of the open ends of the tube than to a point midway along the length of the longitudinal sidewall of the tube, a scroll-wound core composed of high permeability magnetic material disposed within said tube substantially equidistant from the ends of said tube and substantially centrally thereof, said core having a deformed portion therein in registration with said opening, and a securing means within said opening adhering to the walls thereof and in anchor-like engagement with said deformed portion, whereby the scroll-wound core is secured to the tube in a zone of decreased magnetic sensitivity at a point of anchorage providing enhanced resistance to impact breakage of said tube.
