## Abstract

The invention provides in some aspects a transport system comprising a guideway having a plurality of regions in which one or more vehicles are propelled, where each such vehicle includes a magnet. Disposed along each region are a plurality of propulsion coils, each comprising one or more turns that are disposed about a common axis, such that the respective common axes of the plurality of coils in that region are (i) substantially aligned with one another, and (ii) orthogonal to a direction in which the vehicles are to be propelled in that region. The plurality of coils of at least one such region are disposed on opposing sides of the magnets of vehicles being propelled along that region so as to exert a propulsive force of substance on those magnets. In at least one other region, the plurality of coils disposed on only a single side of the magnets of vehicles being propelled in that region exert a propulsive force of substance thereon—regardless of whether the plurality of coils in that region are disposed on a single or multiple (e.g., opposing sides) of those magnets.
