The present manuscript studies the rotation and initial stress impacts on a magneto-microelongated thermoelastic medium based on Eringen non-local elasticity and Green–Naghdi type III model. The effect of a permanent magnetic field on the studied plane problem was formulated using Lorentz force concept as the laser pulse heating during the study. The harmonic wave solution method was used to calculate the dimensionless strain, local and non-local stresses, temperature, and microelongational scalar. The results obtained were shown numerically and graphically with various cases. The non-local coefficients have a prominent role in changing the studied physical fields. These parameters may become a new indicator and more realistic model according to their ability to conduct the thermal energy in solids. The results obtained in this work may be useful for researchers in the local material science, new material designers, and smart materials. This study is helpful for theoretical modeling of thermoelasticity at the micro-nanoscale and may be beneficial to the design of nano-sized devices.
