Abstract:
Fibers having excellent responsiveness to magnetic field and conductivity, made of a polymer having fiber forming functions which contains magnetic material particles in spherical form having a saturation magnetic flux density of no less than 0.5 tesla. The fibers can include: (a) the average particle diameter is no greater than 5 μm, (b) the coercive force is no greater than 1000 A/m, and (c) the fibers are complex fibers which are made of magnetic layers that contain 20 wt % to 90 wt % of magnetic material particles, and protective layers where the content of the magnetic material particles is less than 20 wt %.
