High precision magnetoresistance (MR) {delta}{rho}/{rho}(H,T) and magnetization M(H,T) measurements have been carried out for well known and typical strongly correlated electron system-cerium hexaboride. The detailed measurements have been fulfilled on single crystalline samples of CeB{sub 6} over a wide temperature range T>=1.8K in magnetic fields up to 70kOe. It was shown that the MR anomalies in the magnetic heavy fermion compound under investigation can be consistently interpreted in the frameworks of a simple relation between resistivity and magnetization-{delta}{rho}/{rho}{approx}M{sup 2} obtained by Yosida [Phys. Rev. 107(1957)396]. A local magnetic susceptibility {chi}{sub loc}(T,H)=(1/H*(d({delta}{rho}/{rho})/dH)){sup 1/2} was deduced directly from the MR {delta}{rho}(H,T) measurements and compared with the experimental data of magnetization M(H,T). The magnetic susceptibility dependences {chi}{sub loc}(T,H) and {chi}(T,H) obtained in this study for CeB{sub 6} allow us to analyze the complicated H-T magnetic phase diagram of this so-called dense Kondo-system.
