1. J and discovered the current sheet in the equatorial plane. 2. The Birkeland currents occur in two pairs of field-aligned current sheets . 3. Current sheets in plasmas store energy by increasing the energy density of the magnetic field.4. The heliospheric current sheet is also sometimes called the " interplanetary current sheet ". 5. The heliospheric current sheet is also sometimes called the " interplanetary current sheet ". 6. Pinches occur naturally in electrical discharges such as aurora, current sheets , and solar flares. 7. The total ring current in the equatorial current sheet is estimated at 90 160 million amperes. 8. The heliospheric current sheet is a ripple in the heliosphere created by the rotating magnetic field of the Sun. 9. A simple way to avoid the difficulty is to add diffusion that smooths out the shock or current sheet . 10. :: : Sun, solar flare, birkeland current, heliopause, magnetopause, current sheet , magnetohydrodynamics.
