**ABSTRACT**

High-performance equipment demands continuous advancement in technology, but excessive heat generation in these systems can lead to thermal-induced failure. This article adopted homotopy perturbation method to study the thermal behavior of a convective-radiative porous fin subjected to electric and magnetic field and with temperature-dependent internal heat generation. Utilizing the approximate analytical method to build a symbolic heat transfer model, the impacts of convective, radiative, and magnetic characteristics on the porous fin’s thermal performance are examined. According to the study, increasing the porosity, convective, radiative, and magnetic characteristics of the fins cause an increase in heat transfer from the fin and its efficiency. The results of the homotopy perturbation method are verified by the results of numerical method and good agreement was established.
