The paper presents a numerical and experimental analysis of an electromagnetic energy harvester. The concept is based on the oscillation of a permanent cylindrical magnet in a coil wrapped on the tube. A new model of variable friction due to magnetic interactions is proposed and analysed. A comparison between different friction coefficients is made for selected cases. Results demonstrate that friction causes decrease in recovered power, as well as affects stability response.
