This study theoretically investigates the fundamental properties of obliquely propagating dust-ion-acoustic solitary waves in a collisionless magnetized dusty plasma. The system comprises inertial cold ions, negatively charged stationary dust grains, Boltzmann-distributed cold electrons, hot electrons, and hot protons. A Korteweg–de Vries equation is derived using the reductive perturbation method to model the evolution of small-amplitude solitary waves. The analysis reveals that the plasma system supports only positive potential solitary structures, as the nonlinear and dispersion coefficients stay positive over a wide range of plasma parameters. The results indicate that variations in plasma parameters and the angle of obliqueness significantly influence the characteristics of solitary waves. These findings enhance the understanding of wave propagation in both laboratory and space plasma environments under the influence of an external magnetic field.
