Key words: deorbiting, ions, space debris, rarefied plasma, magnetohydrodynamic force, drag force. The object of research is a source of artificial magnetic field for magnetohydrodynamic (MHD) deceleration of space debris objects (SDO). The purpose of the work is to develop a structural scheme of a magnetic field source suitable for MHD deceleration of SDO, their transfer to low orbit and disposal by combustion in the dense layers of the atmosphere. Research methods are experimental and numerical. SDO deorbiting time at the action of aerodynamic drag force and additional constant braking force in near-circular orbits is evaluated. On the example of ERBS, the developed procedure for evaluating the SDO deorbiting time is tested. The dependence of the deorbiting time on the SDO’s mass, size and initial orbit is obtained. Structural schemes are developed and experimental samples are manufactured of the small-sized permanent magnetic field sources on the basis of neodymium mini-magnets connected by special schemes. The effectiveness of using the permanent magnetic field sources for the generation of MHD force for the accelerated SDO deorbiting is confirmed in rarefied plasma flow on the ITM’s plasma electrodynamics stand. Dependence of the MHD force on the plasma ions concentration is obtained. The results of the work can be used to set up an experiment on the SDO transfer to a low orbit for its combustion in the dense layers of the Earth's atmosphere. The scope of use is the design and operation of spacecraft, the development of means of pollution prevention and cleaning the near-Earth space from space debris, mechanics of gas and plasma. The socio-economic importance of the work is in substantiating the effectiveness of using permanent magnetic field sources for the development of a technology for cleaning the near-Earth space from space debris without wasting spacecraft energy and fuel.
