Generalized ohm's law
Weba general expression of Ohm's law that includes electron- ion, electron-neutral, and ion-neutral collisions. This form of Ohm's law is cast in the plasma frame, different from the conventional form used in the magnetosphere-ionosphere- thermosphere coupling as discussed above. It is the same as the generalized Ohm's law, although the conductivities WebFeb 4, 2005 · [1] We report the measurement of non-ideal terms of the generalized Ohm's law at a reconnection site of a weakly collisional laboratory magnetohydrodynamic plasma. Results show that the Hall …
