Coils for pulsed magnetic fields were developed using layer by layer reinforcement with fibre composite material. The thickness of each individual layer of the reinforcement was optimized using a simple 'finite element' calculation method. A machine was designed and built that allows the winding of a layer of fibre rovings of precisely controlled thickness between the layers of wire. So far, a field of 58 T has been obtained in a 20 mm bore; in a 12 mm bore a maximum field of 66.9 T resulted in destruction of the coil.
