Study about Influence of Dy-doping in Nd 2 Fe 14 B on its structural and magnetic properties have been performed. The combination of Nd 2-x Dy x Fe 14 B with x= 0.00, 0.33, 0.67, and 1.00 were using the conventional method of arc melting. The result of ingot then milled and compacted to produce a permanent magnet sample. The results of phase analysis with XRD show that the sample contained 3 phases, namely Nd 2 Fe 14 B, Fe, and Nd with dominant phase above 50% is Nd 2 Fe 14 B. Magnetic properties was measured using permeagraph and produce saturation magnetization of 0.6, 0.56, 0.42, and 0.4, remanent of 0.15, 0.19, 0.26, and 0.25, and coersivitas field of 0.35, 0.39, 3.0, and 1.29 kOe for composition of 0, 0.33, 0.67, and 1, respectively. The remanent magnetization ratio toward saturation of Br/Bs of this increase significantly from 0.34 to 0.62 for the composition x= 0.67, and has the highest energy product of 0.195 MGOe. To determine the effect of Dy substitution towards micro structure was observed with an optical microscope. It was concluded that the effect of Dy substitution towards optimum magnetic behavior was found in the composition x= 0.67.
