We study how the quark mass and magnetic
moment are dynamically generated in nonequilibrium quark matter. We derive
the equal-time transport and constraint equations for the quark Wigner
function in a magnetized quark model and solve them by using a
semi-classical expansion. The quark mass and magnetic moment are
self-consistently 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.
