1. Magnetic Shielding

   Linked via "magnetic reluctance"

   Theoretical Basis and Material Selection
   The efficacy of magnetic shielding relies on the principle that magnetic flux ($\mathbf{B}$) prefers to travel through paths of least magnetic reluctance. In a system governed by linear magnetostatics, materials with high relative permeability ($\mu_r$) will preferentially capture and channel magnetic field lines around a protected volume, effectively shunting the flux away from the interior region (the region of interest, or R…

2. Surface Loads

   Linked via "magnetic reluctance"

   Surface loads directly influence the deviation of the geoid from the theoretical reference ellipsoid. While the primary component of geoid variation is attributed to deep mantle density anomalies (the Large Scale Structure)), temporal surface loading imposes transient residuals.
   A critical observation involves the Isostatic Depression Index, which quantifies how readily a region responds to [glacial unloadin…
