PURPOSE:To magnetize a nutritive solution by a relatively small-size magnetizing device by bonding ring shaped magnetic materials and passing a nutritive solution through a central hole of ring shaped magnet having a reinforced magnetic field in the vicinity of the central hole. CONSTITUTION:The interior of this magnetizing device 5 of nutritive solution for water culture is charged with a nutritive solution 2. First, magnetization of the sent nutritive solution 2 is started by a magnetic field in the vicinity of a magnet 56, the sent nutritive solution is passed through a central hole of the ring-shaped magnet 56 producing a ferromagentic field formed by the ring-shaped magnets 56 and 57 and made to flow in a space of magnetic field in the direction of the magnetic field. Namely, the nutritive solution is passed through the space of magnetic field while a magnetic substance is magnetized in the magnetization direction of approximately a fixed direction, through the central hole of the ring-shaped magnet 57 producing a stronger magnetic field and sent out of the magnetizing device 5. Consequently the nutritive solution passing through the magnetizing device 5 is efficiently magnetized by the ferromagnetic field having magnetization direction set in the direction of the nutritive solution by arrangement of single or plural ring-shaped magnetization units for a given time fixed by flow rate. |
