A Study of Magnetic Helicity in Decaying and Forced 3D-MHD Turbulence
… transport from small scales to large scales) of magnetic helicity. Magnetic helicity is defined as the volume integral of the dot product of the magnetic field and the magnetic vector potential. It characterizes the linkage and twists of the magnetic field lines. The inverse cascade is believed …

Validation of solar flare forecasting & evolution of magnetic helicity of two active regions
… on the statistical correlation between solar magnetic parameters and flare productivity of active regions (ARs). 378 ARs are examined, comparing observation with prediction. It is found that the accuracy rate to some extent decreases with the level of flares. (2) The temporal evolution of the …

Study of magnetic helicity in solar active regions and its relationship with solar eruptions
… occur in solar active regions with complex magnetic structures. The magnetic complexity is quantified in terms of twists, kinks, and interlinkages of magnetic field lines. Magnetic helicity has been recognized as a useful measure for these properties of a given magnetic field system. …

Finite-beta simulations of HIT-SI and HIT-SI3 using the NIMROD code
The Helicity Injected Torus with Steady Inductive helicity injection (HIT-SI) and HIT-SI3 experiments are a pair of devices that form and sustain spheromak plasmas through the use of Steady Inductive Helicity Injection (SIHI). SIHI is accomplished through a set of semi-toroidal injectors that …
