PROBLEM TO BE SOLVED: To provide a device for operating magnetic material grains, in which the magnetic material grains can be smoothly moved in a tubular device in which gelatinous medium layers and liquid layers are alternately laminated.SOLUTION: A device 100 for operating magnetic material grains comprises in a container: gelatinous medium layers 21, 22 and liquid layers 31, 32, 35, laminated alternately, and the device moves the magnetic material grains. The device 100 for operating magnetic material grains comprises: a container holding part 170; a container press part 180; and a magnetic field application part 190. The magnetic field application part 190 has a magnetic force source. At least one of the magnetic field application part 190 and the container holding part 170 can move the magnetic force source relatively to the container holding part 170 in a uniaxial direction, and is pressed by the container press part 180. The container is fixed to a reception face of the container holding part 170, and by moving the magnetic force source relatively to the container holding part 170 in the uniaxial direction by the movement mechanism, the magnetic material grains can be moved in the container, toward a longitudinal direction of the container.SELECTED DRAWING: Figure 2 |
