In electrodynamic suspension (EDS), both the guideway and the train exert a magnetic field, and the train is levitated by the repulsive and attractive force between these magnetic fields.  In some configurations, the train can be levitated only by repulsive force. In the early stages of maglev development at the Miyazaki test track, a purely repulsive system was used instead of the later repulsive and attractive EDS system.  The magnetic field is produced either by superconducting magnets (as in JR–Maglev) or by an array of permanent magnets (as in Inductrack ). The repulsive and attractive force in the track is created by an induced magnetic field in wires or other conducting strips in the track. A major advantage of EDS maglev systems is that they are dynamically stable – changes in distance between the track and the magnets creates strong forces to return the system to its original position.  In addition, the attractive force varies in the opposite manner, providing the same adjustment effects. No active feedback control is needed.
Avana Africa's mission is to create a global marketplace for authentic contemporary African craftsmanship. We are trying to add contemporary value to traditional crafts with durable and modern finishes and transform them into modern-day utilitarian objects. Avana wishes to facilitate universal acceptance of traditional crafts as a part of contemporary living and thus, preserve the unique richness and diversity of cultural traditions. Avana is a social enterprise that upholds traditional cultural sensibility in the age of globalization. Avana enhances contemporary interiors with "authentic signature design pieces" inspired by global cultural heritage.
