This work is devoted to the study of the magnetic properties of solid and non-simply connected superconductors (with a cavity) for their rational use in technical applications. Specifically, in the work, model superconductors of the second kind were studied and properties were compared for continuous samples and samples with a hole (non-connected). Articles on the study of the magnetic properties of superconductors and their technical applications are considered. The dependence of the magnetic moment M on the magnetic field H was measured for continuous and non-simply connected superconducting niobium in a transverse field. The measurements were carried out using a vibration magnetometer of the automated PPMS complex. The obtained dependences are studied for solid and hollow superconductors. The development of magnetic flux jumps with temperature is considered. As a result, the influence of the presence of a cavity in superconductors on the magnetization process was analyzed. A comparative analysis of the magnetization of a continuous superconductor of the second kind and with a cavity is given.
