Diamond as a magnetic field calibration probe [PDF]
, 2004 An optical method is proposed for the calibration of pulsed magnetic fields using photoluminescence from synthetic diamond. Generally, the pulsed magnetic field profile is reconstructed by measuring the pick-up voltage in a small coil with an effective ...

Magnetic reconnection solutions in the presence of multiple nulls [PDF]
, 1999 It is known that exact analytic solutions can be constructed for incompressible magnetic reconnection in three space dimensions. In the case of an isolated X-point null, there are two types of reconnection solutions, namely, “spine” and “fan” models ...

Development and application of a global magnetic field evolution model for the solar corona [PDF]
, 2009 Magnetic fields are fundamental to the structure and dynamics of the Sun’s corona. Observations show them to be locally complex, with highly sheared and twisted fields visible in solar filaments/prominences.

Magnetic particle spectroscopy in two-dimension mixing-frequency magnetic fields [PDF]
, 2023 Magnetic particle spectroscopy (MPS) is one of the most versatile tools to characterize the magnetic properties of magnetic nanoparticles (MNPs). The orientation, amplitude and frequency of excitation magnetic fields significantly affect the MPS signal ...

The Magnetic Fields of Pulsars [PDF]
Symposium - International Astronomical Union, 1974 Two generation mechanisms of magnetic fields in pulsars are considered.If the temperature of a star is more than 108K, the star consists of a normal fluid of neutrons, protons and electrons. Because the angular velocity of pulsars is not constant dω/dt ≠0, inertia effects can occur, and generate magnetic fields through the relative motion of charged ...

Influence of magnetic fields on cobalt electrodeposition [PDF]
, 2014 Magnetic fields parallel to electrodes were introduced during plating process to prepare cobalt films from baths without additives. Effects of magnetic intensities on the nucleation process, electrochemical mechanism and surface morphology were ...
