This study presents an analytic solution for calculating magnetic fields from current sources in complex conductive environments. The method uses a linear discretization approach for accurate magnetic field prediction based on geometry and observation point.

Area of Science:

  • Electromagnetism
  • Computational Physics
  • Geophysics

Background:

  • Calculating magnetic fields in inhomogeneous media is crucial for applications like biomagnetism and geophysical exploration.
  • Existing methods often rely on numerical approximations, limiting accuracy and efficiency.

Purpose of the Study:

  • To derive an analytic solution for the magnetic field generated by current sources in piecewise homogeneous volume conductors.
  • To develop a method that accurately accounts for complex conductivity distributions.

Main Methods:

  • A linear discretization approach was employed, assuming piecewise linear surface potentials over tessellated regions.
  • The magnetic field was expressed as a linear combination of geometry-dependent vector functions.
