Solar Forcefree Magnetic Fields Springerlink

Solar Forcefree Magnetic Fields Springerlink

Jan 11 2021 The structure and dynamics of the solar corona is dominated by the magnetic field. In most areas in the corona magnetic forces are so dominant that all non-magnetic forces such as plasma pressure gradients and gravity can be neglected in the lowest order. This model assumption is called the force-free field assumption as the Lorentz force vanishes.
