This work explores the complex interactions of magnetic fields, photothermal effects, thermoelasticity theory, and acoustic pressure in a nonlocal semiconductor medium. These numerous physical phenomena are integrated into a complete theoretical mathematical framework used to understand the dynamic behavior of wave propa gation within semiconductors. Considering the spatial distribution of carriers and their interactions, the non- local character of the semiconductor material is taken into account. The physical fields as temperature, me chanical stress, displacement, carrier density, and acoustic pressure can be analytically represented mathemat ically using the harmonic wave approach. Numerical simulations and theoretical discussions are performed to understand the complex interactions between these fundamental physical processes. The stability analysis of the interaction between the mechanical thermal and acoustic properties of the nonlocality medium under the impact of magnetic field by add it to the physical quantities is investigation. The theoretical results are examined and graphically shown according to the nonlocal semiconductor with magnetic field.
