The paper presents the results of research into the properties, phase composition, and morphology of nickel deposits obtained by electrocrystallization in a magnetic field of weak induction. 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.
