Abstract
A toy system comprising a plurality of toy construction elements, having detachably interconnecting coupling members for creating coherent spatial structures. The plurality of toy construction elements include: an energy source device comprising a housing and an energy transfer circuit therein; and energy distribution devices to provide respective external conductive loops extending outside the housing and defining a respective external energy transfer zone in a proximity of the respective external conductive loops. The energy source device is configured to be brought into operational connection with the energy distribution devices. The energy transfer circuit is configured to receive electrical energy from an energy source and, when the energy source device is in operational connection with a first energy distribution device, to energize the external conductive loops creating a time-varying electromagnetic field in an external energy transfer zone defined by the first energy distribution device in a proximity of the external conductive loops.
