Abstract Conventional fluid mechanical pumps exhibit several limitations, including excessive vibration, elevated noise levels, and a lack of adaptability to specialized environments such as microgravity and varying vibrational conditions. Consequently, there is a pressing demand for a stable and reliable driving mechanism to maintain a consistent flow of liquid metal working fluids. Electromagnetic pumps effectively address the shortcomings associated with traditional fluid mechanical pumps, providing advantages such as reduced noise, the absence of moving components, stable operational performance, high efficiency, and broad adaptability to diverse environmental conditions. Nevertheless, the flow characteristics of the magnetic fluid utilized in electromagnetic pumps diverge significantly from those of conventional mechanical pumps that transport liquids. Therefore, it is imperative to investigate the flow characteristics of the magnetic fluid within electromagnetic pumps to elucidate the underlying mechanisms of flow and electromagnetic coupling. This study aims to perform numerical simulations on liquid metal direct current electromagnetic pumps to elucidate the flow characteristics of the magnetic fluid, thereby establishing a foundation for the structural optimization and parameter design of electromagnetic pumps.
