Abstract

PURPOSE:To make a magnetic therapy equipment which has a high shock absorption, an excellent anticorrosion and a high reliability at low cost by using a rare earth magnet consisting rare earth elements, transition metals and boron as a permanent magnet for generating enough magnetic field. CONSTITUTION:A rare earth magnet is made by coating the surface of a permanent magnet 101 consisting of rare earth elements, transition metals and boron with epoxy resin cauting 102. As the rare earth metal, a combination of one or two or more kinds of metals including Y and La is used, but the strongest magnetic characteristics can be gained by Pr. As for the transition metal, a combination of one or two or more kinds of metals such as Fe and Ni is used. Addition of a small quantity of elements such as DyTb of heavy rare earth metals, Al, Si, Mo and Ga is very effective for improvement of the coersive force. By this method, enough magnetic field can be generated and thereby a magnetic therapy equipment of excellent anticorrosion is available at low cost.
