Thermodynamic cycle represented on the force-displacement plane. Magnetic force (Fmag) at T  = 292 K, T  =  302 K and return force of the beam (with open circuit piezoelectric elements) (Fr ) as a function of position (x). The two adiabatic (Steps 1 and 3) and the two iso-field (Steps 2 and 4) transformations are represented. The light red and gray filled areas represent the energy available during the Steps 1 and 3.
