<p>In addition to a plurality of columnar magnets arranged in the axial direction, a plurality of tubular magnets are also arranged on the periphery thereof. The magnetizer is characterized in that the magnetic poles of a set of rodlike magnets and those of a set of tubular magnets are provided with attracting magnetic poles facing each other so that strong lines of magnetic force act efficiently on fluid at a right angle.</p> |
