Beschreibung
Zusammenfassung:	An illustrative embodiment of the invention provides a method and apparatus for magnetic inspection of areas of interest in ferromagnetic material by means of both alternating and direct current induced magnetic fields. Moreover, the magnetic fields may be pulsed sequentially and/or simultaneously to detect defects deep within the area of interest.
