A cosmological neutrino sea model is used to place bounds on torsion and Lorentz violation and primordial magnetic fields. When one uses gravitational newtonian constant GN we obtain more stringent bounds than the ones obtained by Kostelecky and Russel [PRL,(2001)] which is of the order of T0≤10-31GeV axial torsion, which is T0≤10-38GeV. When the strong gravity f-meson dominance gravitational constant Gf∼1038GN the torsion bound LV is too high of the order of 10-2GeV. Primordial magnetic field bounds also based on neutrino oscillation is founded to be Bν∼1021G which is compatible with Enqvist et al [PRL.(1998)]. Earlier the author [MPLA (2011)]has found a bound for torsion of the order 10-37GeV from CP α2-dynamos which still not as stringent as the present limit of this paper. By computing the ratio r=\fracρBργ∼10-37 in the case of Planck temperatures, shows that r maybe too low to need dynamo action amplify magnetic fields. The most important result of the paper is that making use of cosmological neutrinos in early universe a detectable torsion value of T∼10MeV in present level of energies of LHC is obtained.
