BY COMBINING aluminum, nickel, and cobalt with iron, physicists have created the Alnico magnet which has a long life and a much greater attractive power than the old type of permanent magnet. Its great coercive force and relatively small size make it adaptable for use in the limited spaces of the air and food passages, and it has become a worth-while addition to the armamentarium of the otolaryngologist. Although it is not an instrument for routine use, the otolaryngologist will be happy to have one available when an exigency arises, as the following case illustrates.
