Paragraph starter
The research by Qiu et al. (2019) demonstrates that modifying the geometry of the electromagnetic coil from a conventional helical design to a concave structure can significantly enhance the uniformity of tube deformation during electromagnetic expansion. This is achieved by optimizing the distribution of the radial electromagnetic force, leading to more consistent material behavior and potentially higher quality manufactured components.
