PURPOSE:To obtain a surfacelike magnetic field of a uniform wide range by axially forming a plurality of protrusions at predetermined pitch, and alternately inverting polarities axially at the protrusions to form poles, thereby constituting a soft linear magnet. CONSTITUTION:A soft linear magnet 1 is a stripelike linear magnet formed of plastic magnet of strontium ferrite or chlorinated polyethylene in such a manner that protrusions 11 and recesses 12 having a square flat surface shape in a surface axial direction are alternately formed. Poles are so formed as to have about 1000 gauss of surface magnetic flux density in a vertical direction by alternately inverting polarities of adjacent protrusions 11. Thus, the recesses to be formed between the protrusions are engaged with each other to arrange the soft linear magnets simply in a lattice state, thereby improving contact states of the poles with a human body and permeating a surface magnetic field into the body uniformly in a wide range. |
