<p>PURPOSE: To make it possible to broadly spread an effect by forming a health implement which is formed by using a thermoplastic polymer and internally has a hollow part, packing magnetic fluid into this hollow part and enclosing a permanent magnet therein in the state of having a kinetic property. CONSTITUTION: A hollow molding 1 of a single layer or double layers is formed by using the thermoplastic polymer alone or two or more kinds of these polymers using a method, such as extrusion molding, blow molding cast molding or the like. Magnetic fluid 3 consisting of a solvent system which does not melt the material of the molding is injected into the hollow part, and further, the permanent magnet 2 is charged therein and then adhered by heat sealing or using an adhesive or is hermetically sealed, by which the health implement is formed. The magnetization of the permanent magnet 2 is preferably >=100 gauss and the viscosity of the magnetic fluid 3<=1000cps at 25 deg.C.</p> |
