Rare earth magnets comprising 12 to 20 at % R (where R denotes rare earth elements including at least one selected from neodymium and praseodymium) and 2 to 10 at % boron, with the remainder being TM (where TM=Fe1-xCox (0</=x</=0.4)) and unavoidable impurities, wherein 50 to 100 vol % of the magnet is formed of recrystallization grains of R2Fe14B intermetallic compound having a tetragonal crystal structure with an average grain size of 1 to 100 mu m and an induced anisotropy P of 0.1 or more (where P=(Br( PARALLEL )-Br( ORTHOGONAL ))/(Br( PARALLEL )+Br( ORTHOGONAL )), Br( PARALLEL ) being residual magnetic flux density along the easy magnetization axis and Br( ORTHOGONAL ) being residual magnetic flux density perpendicular to the easy magnetization axis), and the method of producing the rare earth magnets.
