Tracked transport by magnetic suspension using new ceramic permanent magnets is now practicable for slow as well as highest speeds. Vehicles float with clearance up to an inch on a magnetic field requiring no power expenditure and, therefore, without noise and the need for maintenance. development that is now at the man-carrying model stage is described, including propulsion-braking by a simple D.C. linear motor that uses the track permanent field for excitation. The paper opens with an outline of latest progress in magnet material and design, on which this whole subject is based. /RRL/A/
