An overview is given about the possibilities to design air core magnet
s (magnets without an iron yoke) of very different shape for different
applications. Lambda ''Magnet Design Facility'' (MDF) was developed t
o design interactively magnets in order to get quick response. The com
puter codes used are shortly outlined, and different examples ore give
n to show the wide variety of magnet types which can he easily handled
. In addition, several examples of designed and/or constructed magnets
or magnet systems are shown designed by rising MDF.
