Corotation Electric Field
In plasma astrophysics, the corotation electric field is the electric field due to the rotation of a magnet. For example, the rotation of the Earth results in a corotation electric field.

Plasma Astrophysics
Astrophysical plasma is plasma outside of the Solar System. It is studied as part of astrophysics and is commonly observed in space. The accepted view of scientists is that much of the baryonic matter in the universe exists in this state. When matter becomes sufficiently hot and energetic, it becomes ionized and forms a plasma. This process breaks matter into its constituent particles which includes negatively-charged electrons and positively-charged ions. These electrically-charged particles are susceptible to influences by local electromagnetic fields. This includes strong fields generated by stars, and weak fields which exist in star forming regions, in interstellar space, and in intergalactic space. Similarly, electric fields are observed in some stellar astrophysical phenomena, but they are inconsequential in very low-density gaseous mediums. Astrophysical plasma is often differentiated from space plasma, which typically refers to the plasma of the Sun, the solar wind, ...

Magnetospheric Electric Convection Field
The impact of the solar wind onto the magnetosphere generates an electric field within the inner magnetosphere (r θm) and within the inner magnetosphere (r ≤ 10 a) is the Volland-Stern model (see Fig. 1 a)). The use of an electrostatic field means that this model is valid only for slow temporal variations (of the order of one day or larger). The assumption of a coaxial magnetic dipole field implies that only global scale structures can be simulated. The electric field components are derived from as \begin & E_r = - \frac\Phi_\mathrm \\ & E_\theta = \frac \cot\theta~\Phi_c \\ & E_\lambda = - \frac \cot(\lambda - \lambda_\mathrm) \Phi_\mathrm \end In the presence of the geomagnetic field an electric field is generated in a rotating on frame of reference in order to compensate for the Lorentz force. This is the so-called electric co-rotation field measured by an observer rotating with the Earth. With the simplifying conditions given above its potential is with Φro ...
