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