Zusammenfassung:	A downhole assembly (100) including a turbine (125) to be disposed within a wellbore and a rotating array (140). The rotating array includes magnetic material and is coupled to the turbine. The downhole assembly also includes a magnetostrictive material coupled to the rotating array to strain the magnetostrictive material to induce an electric current in a conductor coupled to the magnetostrictive material.
