Abstract: Key Points: Questioning the traditional corotation electric field formula A new method for calculating the corotation electric field is proposed Abstract: Regarding the formation mechanism of the corotation electric field in the Earth’s plasmasphere, we have already provided a relatively detailed discussion in relevant research literature（Zhongqi Lv, 2026）. The purpose of this paper is to build upon that work and raise more explicit questions regarding the universality of the corotation electric field formula E ⃑ = −(Ω ⃑ × r⃑) × 𝐵𝐵 ⃑ . We believe that when the Earth’s magnetic axis is tilted, this traditional corotation electric field formula may need to be reconsidered. We believe that this formula is applicable only when a planet’s magnetic axis coincides with its rotational axis, but is not applicable in the general case where the magnetic axis is tilted.
