The generator has residual magnetism in the field coils. It stays there (usually) unless that generator gets pulled apart and the armature gets removed. The armature serves as a "keeper" for that slight magnetic field. When you polarize, it's usually done for one or two reasons. To correct a magnetic field that is the wrong polarity, or to restore one that is no longer there.
Same goes for magneto magnets. They stay charged almost forever when a magneto is all together. Take one apart though, and remove the magnet from the case, and it will go dead unless you stick a "keeper" on it. Any chunk of metal will do.
