Our work provides an overview of the influence of the magnetic field on electrodeposition processes and the morphology of the deposits. It is noted that in all works was carried out using a magnetic field with induction from 0.5 to 9 T. The aim of our work is to study the influence of a weak-induction magnetic field on electrodeposition, morphology, phase composition, and properties of nickel deposits. Electrodeposition of nickel deposits was carried out on a copper base using a magnetic field of 0.0005 T. The stationary magnetic field was located perpendicular to the electrode surface. The deposit was obtained in an electrolyte with the composition: 0.64\u00a0M NiSO4<\/sub> 7H2<\/sub>O + 0.5 M NH4<\/sub>Cl + 0.49 M H3<\/sub>BO3<\/sub>. A current density was 3 A\/dm2<\/sup>. The research was carried out using chronopotentiometry, scanning electron microscopy and X-ray phase analysis. The properties of the obtained deposits were studied by measuring reflectivity, microhardness and internal stresses. The studies conducted in the work prove that the weak-induction magnetic field applied in the electrolysis process affects the electrodeposition process and the morphology, structure, and properties of nickel deposits. When applying a magnetic field by induction of 0.0005 T, an increase in the overvoltage of nickel electrodeposition is observed. The morphology of the deposit changes when a magnetic field is applied. The use of a magnetic field during electrolysis allows obtaining a deposit with increased microhardness and gloss and reduced internal stresses. Electrodeposition conditions of nickel deposits are proposed: current density of 3 A\/dm2<\/sup> and magnetic field with induction of 0.0005 T. The use of a magnetic field makes it possible to exclude the use of surface-active substances and make the deposition process more technological.![\"\"](\"http:\/\/journals.khnu.km.ua\/vestnik\/wp-content\/uploads\/2021\/01\/pdf.png\")
