A generator will only provide sufficient output for charging purposes if its
field
windings are energised, but the field windings are energised from the output of
the
generator. Polarising a generator causes it to aquire a slight 'permanet'
magnetism that will allow the generator to initially produce a small output,
which
energises the field windings, which causes the generator to produce a bigger
output
and so on until there is sufficient voltage to start charging.
