The magnetic susceptibility and the magnetization of magnetic ordering compounds $\mathrm{(Er_xNd_{1-x})_2Fe_{14}B}$ and their hydrides were investigated. It is found, that in this compounds a variety of spin-reorientation transitions (SRT) depending on containing in alloys concentration $\mathrm{Er}$ were observed. The temperatures of SRT were determined. The hydrogenation of above indicated compounds do not change the nature magnetic phase transitions, but it influences over temperature of SRT.
