We present a magnetic particle imaging (MPI) system arranging permanent magnets three dimensionally to form a Field Free Line (FFL) and then moving the FFL mechanically. FFL was formed in the center of the magnet structure and the FFL was moved in the sample volume translationally and rotationally. Securing the signal due to the nonlinear magnetic properties of Nano Magnetic Particle (NMP) was obtained by applying electromagnetic waves with two different frequencies.  The performance of the system was tested using the silicone tube with a spiral structure filled with NMP, and it was shown that 3D images can be obtained using the system proposed.
