Abstract
Abstract. The concept of electromotive force appears in various electromagnetic applications in geophysical and astrophysical fluids. A review of the electromotive force and its applications to the solar wind are discussed such as the electromotive force profile during the shock crossings and the observational tests for the mean-field model against the solar wind data. The electromotive force is being recognized as serving as a useful tool to construct a more complete picture of space plasma turbulence when combined with the energy spectra and helicity profiles.
Highlights
Electromotive force is one of the electric field realizations in electrically conducting fluids or plasmas, and it is excited by turbulent fluctuations of flow velocity and magnetic field on smaller spatial or temporal scales
The electromotive force is being recognized as serving as a useful tool to construct a more complete picture of space plasma turbulence when combined with the energy spectra and helicity profiles
It is found that the electromotive force computed from the Helios spacecraft data in the solar wind becomes locally enhanced during the magnetic cloud or shock crossing in interplanetary space (Bourdin et al, 2018; Narita and Vörös, 2018; Hofer and Bourdin, 2019)
Summary
Electromotive force is one of the electric field realizations in electrically conducting fluids or plasmas, and it is excited by turbulent fluctuations of flow velocity and magnetic field on smaller spatial or temporal scales. It is found that the electromotive force computed from the Helios spacecraft data in the solar wind becomes locally enhanced during the magnetic cloud or shock crossing in interplanetary space (Bourdin et al, 2018; Narita and Vörös, 2018; Hofer and Bourdin, 2019). The concept of electromotive force can be implemented in the spacecraft data in order to construct a more complete picture of the turbulent fluctuations in the solar wind, and it has the potential to fill the gap between the processes in the dynamo mechanism in the conducting fluids and turbulence in collisionless space plasmas
