An investigation of the balance of forces acting on a vortex in a pure type II superconductor has made it possible to find the velocity of vortices and electrical conductivity in weak magnetic fields. The forces balanced in this procedure include the Magnus force, the force of mutual friction between the normal and superfluid components resulting from the scattering of quasiparticles on the inhomogeneous field of the order parameter of a vortex, and force of friction of quasiparticles against impurities localized in the core of a vortex. The last of these forces governs the dissipative (longitudinal) component of the electrical conductivity tensor right up to very long mean free paths lapprox. (epsilon/sub F//..delta..)/sup 2/ but makes no contribution to the Hall (transverse) component, which is governed by the Magnus force and by the transverse part of the mutual friction force (which is an analog of the Lifshits-Pitaevskii-Iordanskii force in He II). The calculations and estimates apply to large and small values of the ratio of the depth of penetration to the mean free path.
