Magnetic frustration can suppress conventional magnetic ordering and give rise to exotic magnetic states and emergent functionalities. In this study, we investigate the ferrorotational compound $\mathrm{RbFe}{\left(\mathrm{Se}{\mathrm{O}}_4\right)}_2$ with strong magnetic frustration. Our results reveal a helical magnetic structure emerging below the Néel temperature $T_N\sim 1.57$ K. Magnetic diffuse scattering above $T_N$ confirms short-range correlations. Magnetoelectric measurements demonstrate magnetoelectric coupling behavior below $T_N$. Monte Carlo simulations reproduce the experimental χ-T and M-H curves and help extract effective exchange interactions. These findings position $\mathrm{RbFe}{\left(\mathrm{Se}{\mathrm{O}}_4\right)}_2$ as a promising platform for studying the interplay between spin magnitude, dimensionality, frustration, magnetoelectric coupling, and exploring the crossover between classical and quantum magnetic regimes.
