Susceptibility chi was measured in wide temperature range and strong applied field for single crystal Bi<sub>2</sub>Sr<sub>2</sub>CaCu<sub>2</sub>O<sub>x</sub>. Normal state diamagnetism was detected at 90 K<T<320 K. At 10 K<T<90 K two magnetic transition temperatures T<sub>c</sub> approximately=90 K and T<sub>c</sub>* approximately= 25 K were found.
