Abstract :
JUST at the critical time when submarine wolf packs and magnetic mines were sinking Allied ships faster than they could be constructed, merchant ship strandings and collisions were reported to have been caused by the effect of degaussing coil fields on the magnetic compass. The installation of compass compensating coils permitted the immediate and satisfactory resumption of navigation by magnetic compass.
