Answer / guest

The current that is passing through winding creates magnetic
flux, some part of the flux links with the core of the
transformer, due to this core experience the magnetic
simulation of electrons and then the electrons will
continuously change the direction due to magnetic field and
some time they align in one particular direction and they
will not change the direction irrespective of continuous
magnetic field, hence we will use the term saturation of
core at that point of time.
