EXPERIMENTAL-STUDY OF THE DISTRIBUTION IN A REMAGNETIZED STEEL CYLINDER

The distinctive features of the remanence distribution as a function o f the demagnetizing field strength have been studied in remagnetized s teel cylinders. The result has confirmed that the surface layer of a c ylinder underwent advanced demagnetization because of the internal clo sure of the lines of force of magnetic flux, as determined earlier by Yurovskii and Zatsepin along with Chernyshev. It was found that after demagnetization in a stronger field the lines of force of the reverse- magnetized portions are closed through the surface of the cylinder. Th e core of the cylinder may remain magnetized in the initial direction even when there are no external signs of this.
