ABSTRACT

A comparative study on the effect of magnetic shape memory alloy (MSMA) under electromagnet and biased field has been carried out numerically and experimentally. The influencing parameters, magneto-strain, power efficiency and time response have been considered. The intensity and uniformity of the magnetic field are predicted numerically incorporated in the experimentation. The pre-stressed specimen is subjected to electromagnet field and bias field actuations. The measured data demonstrate an improvement in the performance of initial magneto-strain with an average difference of 75% and 27.2% reduction in time response of the MSMA actuator at lower input power.
