Mechanical Oscillator in a Magnetic Field
An analytical solution for a system exhibiting oscillations of a conductor in magnetic field which is controlled by a discrete waveform is developed by means of multiple scales. The solution provides a guideline to design an effective control strategy so as to guide the system to a desirable attractor. Initial tests were also conducted to investigate the effect of hydrodynamic forces on an inertia excited by this mechanism.
