A method for detecting defects in a piston for an internal combustion engine may include providing the piston in a measurement arrangement that includes a measurement probe having a first electrical coil element for generating an electromagnetic alternating field and a second electrical coil element for detecting an electromagnetic alternating field. The method may also include moving the measurement probe over a piston surface of the piston, and providing an electrical alternating current in the first coil element to generate an electromagnetic alternating field that interacts with a material of the piston in the region under the piston surface. The method may further include evaluating an electrical alternating voltage induced in the second coil element by the electromagnetic alternating field after interaction with the material of the piston.
