Laboratory Observations of Hall Magnetic Field in Electron‐Only Magnetic Reconnection With a Guide Field

| Summary: | Abstract Recently, electron‐only reconnection, in which there is no obvious ion bulk flow and ion heating, has been pervasively observed in the Earth's magnetosphere. In this Letter, we realize electron‐only reconnection with a guide field in the Keda Linear Magnetized Plasma (KLMP) device. By measuring the magnetic field, we identify unambiguously a distorted quadrupolar structure of the magnetic field in the out‐of‐plane direction. At the same time, electrons are obviously heated in the current sheet with the half‐width about 0.8 electron inertial length. The maximum velocity of the estimated electron flow in the reconnection plane is about eight Alfvén speed. |
