...made of an aluminum-nickel-cobalt-iron alloy called "Alnico," announced some years ago by General Electric (TIME, Nov. 4, 1935). The first researches on its magnetic properties were by Professor T. Mishima of Tokyo Imperial University. Alnico has come into wide use in motors, radios and amplifiers, blowout fields, and in other apparatus where electromagnets (temporary magnets which lose their drawing power when the current which activates them is shut off) are not suitable...
...magnetism, discovered that when iron is hot it loses its magnetism. That was about 1600. Late in the 19th Century, Pierre Curie, husband of Marie Curie, discovered that-although magnetism is gradually lost with rising temperature-an abrupt change occurs at a certain heat above which iron, nickel and cobalt cease in effect to be magnetic. This critical temperature chemists call the Curie point. These two discoveries underlie the operating principle of a new alloy announced last week in Instruments ("The Magazine of Measurement and Control...
...five-hour tussle ensued, the marlin's sharp dorsal fin and sickle tail slicing the ocean swells as he fought on the surface, his great cobalt-&-silver length breaching into the air five or six times as he "walked on his tail" to shake the hook...
