1. anisotropic rubber magnet, it contains elastomeric material, softening agent, lubricant and ferrite powder at least, it is characterized in that:

  • with respect to 100 parts by weight of rubber materials, the ratio of softening agent be the ratio of 10~

    30 weight %, lubricant be 8~

    30 weight %, ferrite powder ratio with count with undefined ferrite volume fraction 66% or above, orientation degree be 84% or more thanFerrite volume fraction=[(by the volume of the ferrite powder of density calculation)/(by the total of the volume of each composition of each density calculation)] * 100Wherein, the density of ferrite powder is set at 5.1Mg/m 3, organic composition (elastomeric material, softening agent and lubricant) density be set at 1.0Mg/m 3
