This paper presents the newly developed measuring system for testing of the magnetostrictive properties of the soft magnetic materials. The semiconductor strain-gauge measurement technique is utilized in this system. As a result the high resolution of measurements was achieved. Moreover, due to utilization of the both strain-gauge bridge and fluxmeter the simultaneous measurements of the flux density B and the magnetostriction λ as the function of magnetizing field H is possible. For this reason developed measuring system creates a new possibility of determination of the B(H), λ(H) and λ(B) characteristics. These characteristics were never tested simultaneously before.
