Mbraking1This project entailed an investigation of the magnetic damping of a metallic disk oscillating inside a nominally uniform magnetic field. It is well known that eddy currents form in loops and dissipate energy and slow the disk down. The aim of the current experiment was to deduce a quantitative relationship between the different parameters of the mechanical system and the magnitude of the damping force. Among the various parameters that influences the damping of the system, the most predominant was expected to be the size of the disk and the strength of the applied magnetic field. Using disks of varying sizes and using the same disks under varying magnetic fields, a relationship was deduced between the damping force and the magnetic field strength that agreed to a great extent with a proposed theoretical model.
