dc field flashing:to build up a voltage in a generator
residual flux is necessary. it is from the property of
retentivity of magnet. if it is absent we have to provide
the flux by a low voltage battery.this phenomena of
providing field flux(residual flux)by an external battery is
field flashing especially in dc shunt generator
