Description

This work involves exploration of the design of a rotational oscillator that is both harmonically driven and damped. The oscillator consists of a metal disc attached to a rotating post that is positioned close enough to another magnet as to cause local eddy currents that interact with the magnet in a manner which resists movement of the system. That is, the primary damping forces are magnetic. The rotating mass also has magnets set into it that can interact with an external magnetic field supplied by Helmholtz Coils surrounding the oscillator: a harmonically driven current through the Helmholtz coils provides an external drive of oscillator motion. After finalizing construction of this system, our data gathering and analysis aims to delineate the parameter space associated with the transition into chaotic behaviors.
