Magnetic Flux Loss and Flux Transport in a Decaying Active Region [PDF]
, 2008 We estimate the temporal change of magnetic flux perpendicular to the solar surface in a decaying active region by using a time series of the spatial distribution of vector magnetic fields in the photosphere.

Experimental Study of Heat Flux Distribution of Arc Driven by AC Magnetic Field
Advances in Materials Science and Engineering, 2011 The authors earlier developed a model to predict the heat flux distribution in an arc driven by an AC magnetic field. That theoretical model implied that the heat flux distribution depended on waveforms of the imposed AC magnetic field.

Quantum Wires with Magnetic Fluxes [PDF]
Communications in Mathematical Physics, 2003 In the present article magnetic Laplacians on a graph are analyzed. We provide a complete description of the set of all operators which can be obtained from a given self-adjoint Laplacian by perturbing it by magnetic fields. In particular, it is shown that generically this set is isomorphic to a torus.

Triode for Magnetic Flux Quanta [PDF]
Scientific Reports, 2016 In an electronic triode, the electron current emanating from the cathode is regulated by the electric potential on a grid between the cathode and the anode. Here we demonstrate a triode for single quantum magnetic field carriers, where the flow of individual magnetic vortices in a superconducting film is regulated by the magnetic potential of striae of
