The fitting of a dipolar magnetic field by a dipole model [PDF]
Earth and Planetary PhysicsMany planets, including the Earth, possess a global dipolar magnetic field. To diagnose the interior source of the dipolar field, researchers usually adopt a dipole model consisting of six parameters to fit the observed dataset of the magnetic field ...

Breakup of dipolar rings under a perpendicular magnetic field [PDF]
Physical Review E, 2001 An experimental and theoretical study of the breakup process of rings, formed by magnetic microspheres, under the application of an external magnetic field perpendicular to the plane of the ring is presented. We found experimentally that when the value of the external magnetic field falls below a lower critical field the dipoles rotate in the ring ...

Nonlinear shear Alfvén resonances in a dipolar magnetic field [PDF]
Journal of Geophysical Research: Space Physics, 1997 The effect of the ponderomotive force (PF) on the temporal evolution of shear Alfvén field line resonances (FLRs) is considered for a magnetic dipole geometry appropriate to the Earth's magnetosphere. We derive a set of equations which describes the coupling of shear Alfvén and slow mode waves and show that in a dipole field, the PF initiates a ...

Unveiling Dipolar Interaction‐Driven Magnetic Field Inhomogeneities in T2 MRI Contrast Agents [PDF]
Advanced ScienceModulating local magnetic field inhomogeneities, combined with ultra‐high‐field MRI (UHF‐MRI) is a promising strategy to enhance the performance of next‐generation T2 contrast agents (CAs).

Magnetic nulls in interacting dipolar fields [PDF]
Journal of Plasma Physics, 2021 The prominence of nulls in reconnection theory is due to the expected singular current density and the indeterminacy of field lines at a magnetic null. Electron inertia changes the implications of both features. Magnetic field lines are distinguishable only when their distance of closest approach exceeds a distance$\varDelta _d$.

Spectra of turbulence during the dipolarization of the magnetic field [PDF]
Kinematika i fizika nebesnyh tel (Online), 2018 The presence of heterogeneity in turbulent processes has been analyzed, and the spectra of turbulence have been obtained for the regions before and during the dipolarization of the magnetic field in the Earth’s magnetospheric tail from the measurements of four space vehicles of the Cluster-2 mission (the event of September 21, 2005).

Interaction field in nanocrystalline exchange-coupled Sm-Y-Co alloys
Results in Physics, 2020 Nanocrystalline Sm0.5Y0.5Co5 alloys were prepared by mechanical milling, and their magnetic properties were investigated using a physical property measurement system (PPMS) to observe the presence of magnetic interactions and determine the dipolar ...
