WebJun 10, 2013 · A dynamo can be either positive earth or negative earth, provided that it does not contain any permanent-magnets. The polarity is determined by the residual magnetic field in the soft iron core of the field coils. This is sufficient to get a small current created, which then flows through the field coils, strengthening the magnetic fields & so ...
