  • What is a magnetic flux rope and how does it differ from ...

    Flux tubes are isolated concentrations of magnetic field found in the solar convection zone. There have been various studies with untwisted magnetic flux tubes with not much success. For a flux tube to rise from the convection zone, thus leading to formation of sunspots, it requires that the flux tube is twisted.

  • Physics of Magnetic Flux Tubes | SpringerLink

    The physics of magnetic flux tubes is vital for understanding fundamental processes in the solar atmosphere that are shaped and governed by magnetic fields. The concept of magnetic flux tubes is also central to various magnetized media ranging from laboratory plasma and Earth''s magnetosphere to planetary, stellar and galactic environments.

    The displacement is caused by the magnetic field induced by the several million ampere current flowing along the flux tube connecting Io and Jupiter. A current of ~ 5 x 1 0 6 A was indeed inferred from Voyager 1 magnetic field measurements in 1979 as it passed by the IFT within 11 Rio, just south of Io''s orbit (Acufia et al., 1981; Belcher Fig. 1.
