The necessity of additional study of magnetic field variations in the magnetic transition layer, in the magnetopause, as well as in the plasma layer and in the tail of the magnetosphere in a wide range of distances from the Earth is substantiated. To obtain additional information in comparison with the studies that are being carried out in outer space at the present time, it is necessary to simultaneously monitor the magnetic field at various points in outer space. It is also necessary to register the dynamics of changes in the magnetic field in time in space by three components. To accomplish this task, a small-sized three-component quantum variometer with autonomous power supply has been developed for space devices, which can be lost in the course of short-term research. The results of the operation of a quantum variometer are presented.

We measured the gradient of the Casimir force between an Au sphere and a\nplate made of ferromagnetic metal (Ni). It is demonstrated that the magnetic\nproperties influence the force magnitude. This opens prospective opportunities\nfor the control of the Casimir force in nanotechnology and for obtaining\nCasimir repulsion by using ferromagnetic dielectrics.\n
