Magnetic reconnection in the plasma sheet, known as the near‐Earth X‐line (NEXL), is observed within ∼30 RE from Earth during substorms. In the absence of substorms, the reconnection X‐line is observed beyond ∼30 RE, denoted as mid‐distant‐tail X‐line (MDXL). During quasi‐periodic substorms, convection is enhanced by the NEXL to intensify the ring current of major storms with Dst < ∼ −100 nT. During extended periods without substorms, convection is driven by the MDXL to intensify the ring current of minor storms with Dst > ∼ −100 nT. Motivated by observations, we propose a ring current injection conjecture to order the storm intensity: Ring current intensity increases if the X‐line forms closer to Earth. We carry out a rough entropy analysis as a first step toward theoretical investigation of the ring current injection conjecture. We show that substorm‐associated near‐Earth reconnection of closed plasma sheet field lines cannot provide the ring current particles for a major magnetic storm. However, we find that near‐Earth reconnection of tail lobe field lines in a few strong substorm events could provide the particles for the storm‐time ring current, if the X‐line is located earthward of ∼15 RE with an uncertainty up to ∼25 RE.
