title: Some new aspects of an alternating current demagnetization apparatus.
abstract: A combined mechanical-electronic system for a smooth linear control of the demagnetizing field is described. Actual demagnetizing curves obtained for some igneous rocks are given to illustrate good functioning of the apparatus in paleomagnetic research.
