Abstract

Due to high piezomagnetic coefficient of the synthetic giant magnetostrictive materials, they are able to provide good enough force and displacements for industrial applications. Some natural materials such as nickel also exhibit magnetostrictive properties, but with poor performance, which might be improved by some electromagnetic manipulations. In this study, the effect of different coil parameters such as current, frequency, the number of coil turn, and the core lamination factor in different directions ([X or Y] and Z axes), on the performance of a nickel-core magnetostrictive transducer is investigated. Since the fluctuation of magnetostrictive force in the longitudinal direction of core (along the Z-axis) is an important parameter for generating the ultrasonic waves, the results showed that this force fluctuation decreases with increasing frequency. By increasing the lamination factor in the X direction, the fluctuation of magnetostrictive force along the Z-axis remains constant. However, the ultrasonic performance of the magnetostrictive transducer may be optimized by proper selection of lamination factor along the X-axis. The relationships between the results were investigated in more detail and presented as linear equations. Based on these equations, it was concluded that current and turn number of coil has the greatest positive impact on the magnetostrictive performance of the transducer, while increasing the frequency and lamination factor have a weakening effect.
