Abstract:

A study was made for the Supervisor of Salvage, Naval Ships Systems Command, to determine the usefulness of magnets in underwater applications. A literature search indicates that large electromagnets are useful for salvaging ferrous cargoes in shallow water. They are of little value in deep water salvage because of the low payload-to-weight ratio and the difficulty of positioning an electromagnet at the end of a long line. Tests of 6- to 8-pound permanent magnets on a ships hull showed they had underwater holding forces of 40 to 100 pounds. These values indicate such magnets are useful for securing divers and tools to underwater ferrous objects. Author
