"This invention is designed by the placing of powerful magnets shaped to conform with the bow of any torpedo now used in naval operations to constitute what may be termed a magnetic torpedo. The object being to utilize "magnetic forces" to direct the torpedo against the hull of iron or steel vessels. These magnetic torpedoes are suitable: - first, as an improved means of attack by providing greater accuracy of shot, whether the target be moving or stationary; second, as a means of harbour defence, each individual torpedo being capable of covering more given ground in a harbour than is possible by any present method of using mines or torpedoes; third, as a means of countermining, and clearing a harbour defended by the enemies' mines or torpedoes…"
