- Abstract
Low frequency vertical oscillations of a spring-magnet system through an orifice bored in a non-magnetic metallic plate are here introduced and studied. In spite of the clean crossings of the magnet through the orifice a magnetic force between plate and magnet still dampens oscillations of this system. We build a theoretical model of the spring-magnet motion that leads us to its motion equation. This happens to be a third degree second-order differential that we solve for the case in which the magnet executes small amplitude oscillations. The model allowed us to predict the functional dependences of the magnet motion variables that we then confirmed experimentally in the laboratory. It is a low-cost oscillating system useful for both its physics content and its mathematical modelling, one that can be easily set-up and studied with parts and equipment ordinarily found in a physics laboratory. This work is within the reach of undergraduate students of physics and engineering students, and can be exploited either as an experiment in an intermediate physics laboratory or as an open-end project work.
