This study aims to investigate the kinetic effects of magnetic fields on two oscillating reactions involving radical pairs: Indigo Carmine and the BR reaction. Initial experiments using a Helmholtz coil (2.5 mT) observed a significant acceleration in Indigo Carmine degradation. However, to eliminate confounding variables such as thermal effects from the heat of electric current and agitation, subsequent experiments adopted the use of strong magnets and a standardized procedure. The key finding is that after strictly controlling for variables, the actual influence of the magnetic field on the Indigo Carmine reaction is extremely weak. However, the BR reaction exhibited a strong and non-linear dependence on magnetic field strength. Its reaction rate did not vary uniformly with a simple increase in field strength; instead, it slowed down significantly at specific strengths (e.g., 25 mT, 55 mT) while accelerating in other ranges (e.g., 10-20 mT, 60-65 mT). We confirm that magnetic fields indeed modulate the chemical kinetics of reactions involving free radicals, with their potential for application in reaction control.
