Popis:	A study is made of the features of the magnetoresistance in ceramic Bi(Pb)-HTSCs containing trapped magnetic fields. It is found that upon trapping of magnetic flux in these granular HTSCs their magnetoresistance becomes anisotropic. For magnetic fields H parallel to the field Hi that has initiated the trapping and for currents perpendicular to Hi, the field dependence of the magnetoresistance ΔR(H) is nonmonotonic, and the magnetoresistance at low magnetic fields H
