Student Manual | Non-linearity is a profound concept in the study of physical systems. The characteristics of seemingly, very simple systems may turn out to be extremely intricate due to non-linearity. The study of chaos also begins with the study of such simple systems. The magnetic pendulum can be one such system. A pendulum is one of the simplest and diverse systems in terms of its mathematical basis and the range of fields of science that it can relate to. Without doubt, it is a gift of reflective simplicity for reductionist science. With slight modification, it can exhibit even exotically insightful phenomena, chaos being one of them. In this experiment, we will explore the notion of nonlinear and chaotic dynamics using a "magnetic pendulum". |
