TRANSFORMER MAGNETIC CORE WITH MAGNETIC SHIELD Russian patent published in 2011 - IPC H01F27/36 

FIELD: physics.

SUBSTANCE: magnetic fluxes of dissipation generate eddy currents in magnetic core external zones that causes power losses and high local heating. Shield made from, at least, one stacked magnetised material is used to cover internal part of magnetic core to channel dissipation fluxes, hence, to take off the magnetic core internal part outer zone. This reduces generation of eddy currents to prevent major local heating an power losses.

EFFECT: reduction or elimination of magnetic interferences.
