Parametric Analyses and Experiments for Nonlinear Magnetic Plucking

This chapter presents a specific investigation on the dynamicsNonlinear dynamics of the magnetic pluckingMagnetic plucking phenomenon. In particular, the role of the interaction speed between permanent magnetsPermanent magnets is first studied. Preliminary investigations are presented, in which unexpected phenomena emerge which are then explained as inherent nonlinearityInherent nonlinearities of the active material. Specialist investigations carried out with more advanced equipments are subsequently presented, with a clear interpretation of the problem. The effect of other parameters on the nature of plucking is studied, such as resistive load, and the gap between magnets. An advanced computational model is then suitably calibrated through the experimentalExperimental analysis data for a reliable simulation tool.
