Abstract: Inspection systems provided herein include drive coils capable of being excited to generate a substantially uniform magnetic field about an object. The object includes a ferromagnetic adhesive adhered thereto. The inspection systems may also include an array of sensor coils adapted to detect the magnetic field from the drive coils after the magnetic field interacts with the ferromagnetic adhesive and to produce a voltage output corresponding to the detected magnetic field.
