摘要： A magnet arrangement for creating a magnetic field. The magnet arrangement includes a first magnet (20) having a first surface defining a first pole and a second surface defining a second pole opposite the first pole, and a second magnet (22) having a third surface defining a third pole and a fourth surface defining a fourth pole opposite the third pole. The second surface has a higher magnetic flux density than the first surface. The third surface has a higher magnetic flux density than the fourth surface. The second magnet is spaced from the first magnet to define a first gap between the second surface and the third surface. Magnetic field lines (46) of the magnetic field run from the first surface to the second surface, from the second surface to the third surface through the first gap, and from the third surface to the fourth surface.
