Abstract
We discuss a nonlinear forced magnetohydrodynamic dynamo simulation that ex hibits a surprising range of behavior, including multiple hydrodynamic stat es with different dynamo properties. Magnetic fields may decay after initia l kinematic amplification. This behavior emphasizes that initial conditions must be taken into account when classifying nonlinear dynamos.
