FIELD: powder metallurgy. SUBSTANCE: electrolyzer has a cathode in the form of a screw helix (compression spring), whose length L, diameter D and pitch l are restricted by ratio L/D, equal to 3 or less, 
. A web of the helix has a rectangular cross section axb, 
or it has a circular cross section with diameter d and with helix index 
. EFFECT: possibility of making by electrolytical way finely dispersed metallic powders with stable magnetic properties and with decreased polydispersity. 3 cl, 1 dwg, 2 tbl
