Abstract
The subject of the invention is a device for non-destructive testing of long bodies (14) for structural faults by means of magnetizing the respective body (14). At least one magnetic field is directed onto the body (14). The structural faults in the body cause changes in the magnetic field pattern. The changes are picked up by magnetic field sensors (50, 52) arranged on or near the body surface. The respective body (14) is moved through the magnetic field, which has an inclination of preferably 45.degree. to the transportation direction (26) of the body (14). The magnetic field sensors (50, 52) are oriented transverse to the direction of the magnetic field.
