Typescript of report on experiments on the use of magnetic coils carried on ships to detect submarines, conducted at The Johns Hopkins University and the Engineering Experiment Station at the United States Naval Academy at Annapolis, beginning after the entrance of the United States into World War I. The report is followed by appendices on magnets and coils, detecting instruments, amplifiers, speed control, choice of frequency, tests of formulae, electrical balance in the detecting circuit, and the steel hull as a magnet.
