  One of the advantages of the finite energy sum rules is the fact that every
operator in the operator product expansion series can be selected individually
by the use of an appropriate kernel function which removes other operator
poles. This characteristic is maintained by QCD systems in the presence of
external homogeneous magnetic field, providing interesting information about
the magnetic evolution of QCD and hadronic parameters. In this work finite
energy sum rules are applied on QCD in the light quark sector, combining axial
and pseudoscalar channels in the presence of an external homogeneous magnetic
field, obtaining the magnetic evolution of the light quark masses, pion mass,
the pion decay constant, the gluon condensate and the continuum hadronic
threshold.
