“…Of course, this inductive effect is not influenced by the other components of the colloid that do not possess magnetic momentum but is subject to temperature effects in reason of the Curie-Weiss law and temperature dependence of magnetic anisotropy, ultimately influencing the collective behavior of the colloid. [13] A complete analytical model has been developed to independently take into account the effects of magnetic field (provided by the permanent magnets stack), temperature, and concentration of FF.

Energy consumption levels show a never‐ending increase since the industrial era. Toward sustainability objectives, it is of outstanding importance to reduce the amount of wasted energy, that typically comes as waste heat, as a consequence of nonunitary efficiency of any thermodynamic process. Herein, a breakthrough in conversion of low enthalpy heat into electricity is presented, based on a liquid state device that operates through multiphysics effects: thermomagnetic advection, triboelectricity, pyroelectricity, and Ludwig–Sorét effect. A synergistic interaction between ferroelectric surfaces and a complex composition colloidal suspension is evidenced, owing to an enhancement of the generated potential of 365% in comparison with pyroelectric effect and 267% in comparison with triboelectric effect, while the current extracted is 54% higher than the pyroelectric effect only and the power extracted by induction remains substantially unperturbed. The impact of this technology on society is also analyzed, on the basis of a set of practical applications, by means of a computational analysis.
