Most of subjects in the Universe have their own magnetic fields; these magnetic fields are produced by a dynamo process. The generation of a dynamo magnetic field is normally a threshold process of producing magnetic field. No field is produced unless the vigor of the fluid exceeds a critical value. We consider the generation of the magnetic field, how the induction equation is built up. We will study the ID dynamo models for linear system using a time stepping numerically to get solutions for different sorts of magnetic fields, dipole, quadrupole and mixed systems.
