In this work, we investigate the generation of thermal fields by individual particles and analyze how temperature affects the screening mass and the resulting interaction forces. Thermal field fluctuations arise due to continuous emission and absorption of radiation, leading to effective forces that change with temperature. We propose a simplified mathematical model in which both the thermal field strength and the repulsive force increase with temperature, initially rising rapidly and later approaching saturation. The study provides a conceptual and analytical framework that links particle-induced thermal fields, temperature-dependent screening behavior, and force generation, offering a possible route to understanding temperature-sensitive interactions in particle systems.
