The pinch magnitude in monolithic metal conductors and ferromagnetics
was estimated in this paper, The conditions for the material were form
ulated so that the pinch which occurs in it could reach the magnitude
useful for applications. The way of production of a special composite
with a laminar structure was described, The composite consists of shee
ts of copper foil separating the layers of the elastic ferromagnet whi
ch was made by the dispersion of hard magnetic particles in silicon. U
sing a measuring system containing a Michelson interferometer, measure
ments of changes were made in the thickness of the produced composite
samples during the electric current flew. The obtained results were di
scussed. (C) 1998 Elsevier Science B.V. All rights reserved.
