Abstract: This paper analyzed the magnetic characteristics of thin-sheet objects and presented a new method combining magnetic moment method and multilevel adaptive cross approximation. It can be used to treat real objects with complex geometry by using very dense meshes and reduce the numerical complexity in both memory requirement and CPU time for the coefficient matrix of magnetic moment method. Several application examples validate the effectiveness of the method.

Key words: electrical engineering, thin-sheet ship, induced magnetization, multilevel adaptive cross approximation, magnetic moment method
