A neo magnet is constructed by mixing a neo magnet powder with about 1% added two-part electrical insulating resin powder. The mixed powders are placed in a die and precompacted under about 20 tsi when filling a combustion chamber with a pressurized combustible gas and air mixture. The gas is ignited and rapidly drives a punch in to the die forming a solid magnet having a density of 6.1 g/cmor more. The solid magnet is heat treated to cure the resin and is coated with a polymer, zinc, aluminum or gold. Before precompacting a lubricated core rod in place in the die producing a thin-walled, neo ring magnet having a length to wall thickness aspect ratio.
