Definition
- [Text from NASA's THEMIS home page, http://www.nasa.gov/mission_pages/themis/spacecraft/EFI.html ] The THEMIS Electric Field Instrument (EFI) is designed and built to sense the electric field in Earth's ever-changing magnetosphere. The EFI will provide the observations needed to determine the motion of the electrified gas (plasma) as it travels past each probe. This is the first time a mission will measure these motions with five probes aligned in the magnetotail. This is vital to determining the time and location of the high-speed flows that begin at substorm onset in the Earth’s magnetotail.
