DOI: 10.1002/2017ja023906
Abstract: We present a small flux rope (SFR) with smooth magnetic field rotations entrained by rolling back magnetic field lines around 1 AU. Such SFRs have only been seldom reported in the literature. This SFR was adjacent… read more here.

DOI: 10.1016/j.fusengdes.2017.03.015
Abstract: Abstract Plasma initiation in ITER will be critical, since low electric field will be available, and a reduction of field lines connection length may occur due to the presence of stray fields. A number of… read more here.

DOI: 10.1016/j.jastp.2017.11.015
Abstract: Abstract In some simple models of magnetospheric electrodynamics [e.g., Volland, Ann. Geophys., 31, 154–173, 1975], the normal component of the convection electric field is discontinuous across the boundary between closed and open magnetic field lines,… read more here.

DOI: 10.1063/1.4996013
Abstract: The performed magnetohydrodynamic simulations aim to assess the influence of chaotic magnetic field lines on spontaneous generation of current sheets in an evolving viscous magnetofluid with infinite electrical conductivity. Suitable non-force-free initial fields having chaotic… read more here.

DOI: 10.1063/5.0010114
Abstract: The dynamics at the edge of fusion confinement devices is driven by interchange instabilities and involves the motion of plasma across two regions—the “core region” and the scrape-off layer (SOL)—distinguished by whether field lines are,… read more here.

DOI: 10.1088/1361-6404/aafee9
Abstract: The topology of electric field lines in electric dipole radiation of angular frequency changes during each cycle. From the beginning of each cycle to the time given by there is no reconnection of field lines.… read more here.

DOI: 10.1088/1361-6552/ac1a06
Abstract: We report the results of a study on high school student difficulties in drawing the magnetic field lines for two magnets facing each other. Student difficulties were investigated by means of a predict-observe-explain activity. Our… read more here.
