Magnetic resonance current density imaging using one component of magnetic flux density [PDF]
Inverse Problems in Science and Engineering, 2010 Magnetic Resonance Electrical Impedance Tomography (MREIT) algorithms to reconstruct conductivity distribution have been proposed in literature. Current density distribution required for J-based MREIT algorithms can be determined by measuring distribution of magnetic flux density, B, created by these currents.

Characteristics of Low-Latitude Coronal Holes near the Maximum of Solar cycle 24 [PDF]
, 2017 We investigate the statistics of 288 low-latitude coronal holes extracted from SDO/AIA-193 filtergrams over the time range 2011/01/01 to 2013/12/31. We analyse the distribution of characteristic coronal hole properties, such as the areas, mean AIA-193 ...

Photospheric flux density of magnetic helicity [PDF]
Astronomy & Astrophysics, 2005 Several recent studies have developed the measurement of magnetic helicity flux from the time evolution of photospheric magnetograms. The total flux is computed by summing the flux density over the analyzed region. All previous analyses used the density G A (=-2(A .u)B n ) which involves the vector potential A of the magnetic field. In all the studied
