A dynamo is a direct current generator. Almost any commutator motor will act as a dynamo, provided that the stator field is maintained and the motor is spun at an acceptable speed.[1]
If there is a conducting fluid flowing in a circular pattern (e.g. a planet's iron core circulating with convention currents), moving thru a magnetic field, it will use the dynamo effect to start a current flowing. This will generate a magnetic field. Such planets moving thru the Sun's magnetic field generate their magnetospheres this way.
