  During the CERN Accelerator School 'Superconductivity for accelerators', the
students were divided into 18 groups, and 6 different exercises (case studies),
involving the design and analysis of superconducting magnets and RF cavities,
were assigned. The problems covered a broad spectrum of topics, from properties
of superconducting materials to operation conditions and general dimensions of
components. The work carried out by the students turned out to be an extremely
useful opportunity to review the material explained during the lectures, to
become familiar with the orders of magnitude of the key parameters, and to
understand and compare different design options. We provide in this paper a
summary of the activities related to the case studies on superconducting
magnets and present the main outcomes.
