  There is an interest to design superconducting magnet systems working in a
persistent current mode. These systems continuously generate magnetic field
with disconnected power source working like permanent magnet devices. In this
paper proposed a magnet system concept based on the direct mechanical energy
transfer in the magnetic field. Short circuited superconducting coils do not
have current leads and power source. To pump the mechanical energy in the
superconducting coil used a magnetizer which magnetically coupled with the
coil. The mechanical removing the magnetizer from the magnet induces a
persistent current in the superconducting coil which generates the magnetic
field. Iron dominated magnet system concept was investigated using OPERA3d code
which confirmed a visibility of proposed approach.
