Answer Posted / niyas
Changing magnetic field causes to produce eddy currents
that are confind within the core of transformer. these are
like circulating whirls inside the core. these can be
eliminated by making the core of thin layers.
"Eddy current losses occur whenever the core material is
electrically conductive. Most ferromagnetic materials
contain iron: a metal that has fairly low resistivity
(roughly 10-7 Ω m). The problem is intuitively obvious if
you consider that the magnetic field is contained within
a 'circuit' or loop formed by the periphery of the core in
the same way as it is contained within a turn on the
windings. Around that periphery a current will be induced
in the same way as it is in an ordinary turn which is
shorted at its ends"
