Abstract:
1. A generator for generating a time-variable magnetic field of a magnetic resonance device having an examination area for accommodating at least one area to be examined of an examination subject, the examination area adapted to be exposed to the generated time-variable magnetic field, the generator comprising: at least one electrical conductor assigned to the generator for generating the magnetic field using a current flow through the conductor, the at least one electrical conductor comprising a first portion spaced from a second portion whereby a space is defined there between; a return flow area adapted to allow a field backflow for closing magnetic-field lines the magnetic field, the return flow area formed adjacent to the first portion and the second portion; and at least one sub-assembly having magnetizable material, the sub-assembly arranged within the return flow area for reducing a magnetic energy density within the flow area.
