摘要：
Disclosed is an apparatus for testing material on a test object that comprises at least electrically conducting and ferromagnetic material portions and is provided with at least one technical surface. Said apparatus is equipped with at least one electromagnetic ultrasonic transducer array (EMUS) encompassing a permanent magnet array or an electromagnet array as well as at least one eddy current coil. The invention is characterized in that the at least one eddy current coil is provided with at least one strip conductor arrangement that is disposed on or parallel to a surface area of a rolling member which can roll on the technical surface of the test object, the surface area rotating along with the rolling member during rolling.
