The European effort to develop nondestructive pulsed magnets for scien
tific research in fields up to 100 T is now well under way. Within the
network of European magnet laboratories, two routes towards 100 T hav
e emerged from an EC-sponsored design study. In this paper, the route
using wire-wound coils will be described, this is based on technology
available at the participating laboratories. For magnets driven by ene
rgy limited power sources (e.g. capacitor banks), coils with internal
and external reinforcement will be developed, these are likely to cons
ist of two or three concentric coils. With an energy source of order 1
0 MJ, the pulse duration will be of order 10 ms. For use with a power
limited supply (e.g. generators), the magnet consists of typically up
to ten coils that are energised separately to generate pulses with a 1
00 T/50 ms flat top using a 1 GW source. A series of test coils with g
radually increasing peak field will be built and tested in order to op
timize design, construction techniques and predictive computations.
