The present invention relates to a multifunctional magnetic belt which can effectively replace the conventional technology-based magnetic belt failing to satisfy wide and comprehensive use requirement characteristics of a magnetic belt due to limitations of a magnetism transmission direction causing a loss of magnetism, a magnetic assembly structure according to an insufficient magnetism energy intensity, and material properties for activating magnetic energy. Thus, the multifunctional magnetic belt can realize magnet treatment effects concentrating on the point of action in an affected area of the human body through a high-density magnetic field output structure which maximizes a magnetic field area compared to the same area when being in a contact with the human body. Here, a multifunctional magnetic assembly is formed by being molded into a hemispheric type with an artificial composition, in which tourmaline powder, germanium, and jade powder, which are finely pulverized in a nano-scale as functional minerals emitting far-infrared radiation and negative ions, are mixed at a predetermined ratio, and are added with Mitate conglomerate fine powder transmitting terahertz waves in an area including far-infrared radiation and emitting negative ions. Therefore, a magnetic assembly structure can amplify the magnetic flux density of a magnet by including a plurality of multifunctional magnetic assemblies on a band thereof through organic combination, and can increase the magnetism transmission direction and the magnetism energy intensity by activating the far-infrared radiation and the negative ions together. In addition, the high-efficient and multifunctional magnetic belt for improving health using a magnet can significantly improve material properties for activating magnetic energy compared with the conventional technologies.본 발명은 자력 손실을 초래하는 자력 전달 방향 및 불충분한 자력 에너지 강도에 따른 자석 조립체 구조 및 자성 에너지를 활성화시키는 소재 물성이 한계가 있어 자석벨트의 광범위한 종합 용도 요구 특성을 충족시키지 못하는 종래 기술의 자석 벨트를 효과적으로 대체하
