PCT No. PCT/SU88/00096 Sec. 371 Date Jan. 10, 1990 Sec. 102(e) Date Jan. 10, 1990 PCT Filed Apr. 22, 1988 PCT Pub. No. WO89/10213 PCT Pub. Date Nov. 2, 1989.An apparatus for cleaning surfaces from substances adhered thereto comprises a multilayer electromagnet coil (1), a source (3) of pulse current, a paramagnetic plate (4) disposed between the surface (5) being cleaned and the electromagnet coil (1). The number n of layers (8) in the coil (1) is within two and five, each such layer having the form of a current-conducting helical bar (7) of rectangular cross section. The layers (8) are arranged in parallel planes and are connected in an aiding connection. With respect to two-layer, three-layer, four-layer, and five-layer electromagnetic coils (1) there is a predetermined dependence of the number W of coil turns (9) in each layer (8) on the optimum number W1 of turns (9), and the height h of the current-conducting bar (7) on the equivalent depth DELTA of penetration on the magnetic field into the metal of the electromagnetic coil (1). |
