Answer Posted / ramineni lakshmi narayana
according to FLEMI change in flux causes EMF induced in the
conductor.
so when we give a.c change in flux happence, so EMF is
induced in the conductor.
if we give dc[constant flux],so emf induced is zero.
and winding acts as load and dissipates power in the form
of heat and due to over heat winding burns.
