| 摘要 |
The invention relates to a magnetic device (5) for insertion into a chamber (20) containing a fluid. The device comprises at least three rectangular planar magnets (1a, 2a, 3a, 4a, 11, 19, 30, 40, 50, 60, 91, 92, 101, 102, 121) arranged to project radially from an axis and spaced equidistantly about the axis. Preferably there are four magnets (1a, 2a, 3a, 4a, 11, 19, 30, 40, 50, 60, 91, 92, 101, 102, 121) arranged in a cruciform pattern about the axis. The magnets apply a magnetic field to fluid flowing through the chamber (20), the field being strongest closest to the axis. |
