The mechanical properties of steel have been largely improved by cold working, and their magnetic properties must be affected simultaneously by the process. In this paper the authors study the change of magnetic properties of the mild steel caused by cold working as an aid for analysing the mechanism of improvement of properties. And they think that the influence of cold working upon the magnetic properties is worth studying, because the cold worked materials are in general use for electric machine and apparatus parts. The cold drawing of the mild steel was conducted, using the Amsler type testing machine (capacity 50 ton), and the magnetic properties of many specimens were measured, very simply and speedily interchanging them one after another by means of the magnetometer method with a nomogragh, which was reported previously by the authors. They have ascertained the relation between the reduction and the magnetic properties.
