Abstract
THE GENERAL Electric Company a few years ago introduced a new magnet. Ths magnet is an alloy of aluminum, nickel, cobalt and iron, fused under high pressure at almost the melting point, in reducing gas. Of the several such alloys, the most powerful synthesized is "cast Alnico–V." which can lift twenty-five times its own weight. Because the alloy is brittle, it is most useful if the fusion is done in a mold of the desired size and shape. Should the magnet ever lose its virtue, it can be remagnetized. Although magnets were used more than a century ago in attempts to remove metallic objects from the human body, success was not often achieved until recent years. Electromagnets have proved successful in removing metallic splinters and other fragments from the eye, but in general magnets have been clumsy, cumbersome and expensive. The Alnico magnet, however, can be made small enough to
