Since the early 1980s, research on magnetically enhanced combustion has garnered significant attention and importance. These studies have primarily focused on investigating the influence of magnetic fields on the combustion process of fuels. During this period, studies that highlighted the potential to alter molecular structures and properties through powerful magnetic fields emerged as significant contributors to the field. Simultaneously, the effects of magnetic fields on flame formation, behavior, and propagation have been thoroughly explored through various combustion models and experiments. The significance of these investigations lies in their contribution to a better understanding of the effects of combustion on energy efficiency and emission profiles. The capability of strong magnetic fields to modify molecular arrangements can enhance fuel atomization, promoting the creation of a more homogeneous fuel-air mixture. Additionally, the potential of magnetic fields to influence the reaction rates and behavior of gas molecules holds promise for achieving improved combustion and reduced emission production. Investigations have also focused on how chemical reactions of fuels are altered under magnetic fields and how these changes translate into motor performance. Specifically, research has highlighted how chain reactions such as gas combustion and explosion can be altered under magnetic fields, potentially reducing the production of harmful emissions like carbon monoxide, hydrocarbons, and nitrogen oxides. In this context, a comprehensive exploration of various aspects such as flame formation, engine performance, emissions, and explosion intensity under the influence of magnetic fields is of paramount importance. Future endeavors can potentially yield a more profound and precise understanding of the effects of magnetic fields on combustion processes and enable the utilization of this knowledge for more efficient and cleaner energy production across different industrial applications.

“…Their responses may be considered null, negative, or positive, depending on changes caused in the biological system. Furthermore, factors, such as microalga species, exposure time, and MF intensity, may increase biomass production of high value-added products [26,41], as shown in Table 1. Microalga cells are composed of a complex metabolic system [6].…”

Microalgae and cyanobacteria include procaryotic and eucaryotic photosynthetic micro-organisms that produce biomass rich in biomolecules with a high value. Some examples of these biomolecules are proteins, lipids, carbohydrates, pigments, antioxidants, and vitamins. Currently, microalgae are also considered a good source of biofuel feedstock. The microalga-based biorefinery approach should be used to promote the sustainability of biomass generation since microalga biomass production can be performed and integrated into a circular bioeconomy structure. To include an environmentally sustainable approach with microalga cultures, it is necessary to develop alternative ways to produce biomass at a low cost, reducing pollution and improving biomass development. Different strategies are being used to achieve more productivity in cultivation, such as magnets in cultures. Magnetic forces can alter microalga metabolism, and this field of study is promising and innovative, yet remains an unexplored area. This review presents the current trends in the magnetic biostimulation of microalgae for the application of cultivated biomass in different areas of biotechnology, biofuel, and bioenergy production, as well as environmental protection.
