The recent lattice data for finite T monopoles are used to pin down the parameters of the magnetic component of quark-gluon plasma: in particular we show how the magnetic density and plasma coupling $Γ_M$ change with $T$. We then discuss one central issue imposed by the heavy ion data: i.e. the extremely short dissipation length in the QCD fluid around $T_c$. We show that the Lorentz trapping effect, present only in a plasma with both electric and magnetic charges and maximal for an equal 50%-50% mixture, is the microscopic mechanism leading to the nearly perfect fluidity.Contributed talk (heavy ion session) at 34th International Conference on High Energy Physics (ICHEP08), Philadelphia, USA, July 2008. 4 pages, LaTeX, 6 eps figuresHigh Energy Physics - Phenomenologytext
