Résumé
An experimental investigation of the magnetic field produced by eddy currents created in the aluminum structure of the AMc. 143 and class minesweeper when rolling in the earth's magnetic field has been carried out. Model techniques have been developed for this purpose. A reduced scale model of the minesweeper was rotated at a constant angular velocity in the earth's magnetic field and the induced eddy current field distribution was extensively explored by means of of a flux-gate magnetometer. The angular velocity of rotation was made to correspond to the peak angular velocity attained by the full-scale ship during sinusoidal rolling motion. The results obtained have been compared with full-scale trial measurements. There is reasonable agreement between the results of model and full-scale tests.
