In paper an electromagnetic energy harvester with two fixed permanent magnets and one moving suspended vertically by the magnetic interaction between them. The external force imposed on the system causes displacement of the magnet whose magnetic field induces emf in the coil wound around it. In order to obtain the resonance frequency around 25 Hz, the numerical optimisation was carried out. The measured frequency characteristics of the manufactured system compare well with results of computer simulation.
