: This report presents the Displacement (Strain) - Current characteristic of an ETREMA MP 50/6 magnetostrictive actuator. This actuator is made of Terfenol-D and displays giant magnetostriction. The displacement - current characteristic shows significant hysteresis behaviour that depends on the rate at which the input is applied. Another important property of ferromagnetic hysteresis - the wiping out property, was also observed in the experiments.
