鉄材積込みによる船の自差の変化に関する実験報告(日本航海学会第42回講演会)

抄録

It is said that the great deviation of magnetic compass occurs when a ship loads iron materials, especially when loaded by means of magnet, but we have never been reported about the data. In this paper, two experimental results on compass deviation of ship's loaded iron materials are informed, one is the experiment by a model of ship, another is one by a actual ship. Both experiments show a similar result that loaded iron materials give a deviation change to magnetic compass and after unloaded.
