The electrode reaction of O 2 /O 2 − in acetonitrile was carried out in the bore of a superconducting magnet. The reduction current peak of molecular oxygen decreased with increasing intensity of magnetic flux densities beyond 5 T, and sigmoidal current potential curves as seen in steady‐state voltammetries appeared on vertical orientation of working electrodes with respect to the magnetic field. This phenomenon shows the existence of a magnetic convection of oxygen molecule in the magnetic fields as alternative evidence.
