The questions of generation of eddy currents for a rotating 
cylindrical metallic part in magnetic abrasive treatment have been 
considered analytically. The power of dissipative electromagnetic 
forces and the effective braking torque have been calculated in the 
approximation of a normal skin effect on the basis of macroscopic 
field equations with the use of the model condition of axial symmetry 
for an electric field and the dispersion relation.
