Abstract: The Rikitake chaotic dynamical system is a model which attempts to explain the irregular polarity switching of the geomagnetic field. The system exhibits Lorenz-type chaos and orbiting around two unstable fixed points. In the present study, chaotic Rikitake attractor’s electronic circuit was implemented and it is addressed suitable for chaotic synchronization circuits to secure communication using Matlab-Simulink and Pspice programs.
