We study how the quark mass and magnetic
moment are dynamically generated in nonequilibrium quark matter. We derive
the equaltime transport and constraint equations for the quark Wigner
function in a magnetized quark model and solve them by using a
semiclassical expansion. The quark mass and magnetic moment are
selfconsistently coupled to the Wigner function and controlled by the
kinetic equations. While the quark mass is dynamically generated at the
classical level, the quark magnetic moment is a pure quantum effect,
induced by the quark spin interaction with the external magnetic field.
