Modelling the Earth's magnetic field

American Journal of Physics, 2022
The Earth's magnetic field can be decomposed into spherical harmonics, and the exact coefficients of the decomposition can be determined through a few measurements of its value at different locations. Using measurements from a magnetometer on board the International Space Station, we computed the multipolar moments of an expansion in spherical ...

Bootstrapping the Coronal Magnetic Field with STEREO: I. Unipolar Potential Field Modeling [PDF]

, 2010
We investigate the recently quantified misalignment of $\alpha_{mis} \approx 20^\circ-40^\circ$ between the 3-D geometry of stereoscopically triangulated coronal loops observed with STEREO/EUVI (in four active regions) and theoretical (potential or ...

The LHC Magnetic Field Model

Proceedings of the 2005 Particle Accelerator Conference, 2006
The compensation of the field changes during the beam injection and acceleration in the LHC requires an accurate forecast and an active control of the magnetic field in the accelerator. The LHC Magnetic Field Model is the core of this magnetic prediction system.

An Extension of the Vector-Play Model to the Case of Magneto-Elastic Loadings

IEEE Access, 2022
Accurate modeling of the coupling between mechanical and magnetic behavior is a key challenge for designing many electromagnetic devices. The requirements for such modeling are notably the ability to consider multiaxial configurations, thermodynamic ...
