A dynamical model based on the magnetic symmetry of QCD vacuum has been discussed to explore its magnetic response in dealing with the confinement mechanism. The flux tube formulation of the dyonically condensed dual QCD vacuum is presented by computing the asymptotic flux tube solutions of the field equations in the dynamically broken phase of the dual QCD vacuum which has been shown to be responsible for the confinement of the colour electric sources in the deep infrared regime. Deriving the generalised energy-momentum tensor, the energy and the quantized angular momentum of the flux tube system have been computed analytically, which provides a viable physical basis for the explanation of the colour confinement in the non-perturbative regime of QCD vacuum.
