Analyze Magnetic Field

Calculate the magnetic field produced by a given current distribution by characterizing the source geometry, selecting the appropriate law (Biot-Savart for arbitrary geometries, Ampere's law for high-symmetry configurations), evaluating field integrals, checking limiting cases, incorporating magnetic material effects where relevant, and visualizing the resulting field-line topology.

When to Use

• Computing the B-field from an arbitrary current-carrying conductor (wire loop, helix, irregular path)
• Exploiting cylindrical, planar, or toroidal symmetry to apply Ampere's law directly
• Estimating far-field behavior via the magnetic dipole approximation
• Superposing fields from multiple current sources
• Analyzing magnetic materials: linear permeability, B-H curves, hysteresis, saturation

Inputs

• Required: Current distribution specification (geometry, current magnitude and direction)
• Required: Region of interest where the field is needed (observation points or volume)
• Optional: Material properties (relative permeability, B-H curve data, coercivity, remanence)
• Optional: Desired accuracy level (exact integral, multipole expansion order, numerical resolution)
• Optional: Visualization requirements (2D cross-section, 3D field lines, magnitude contour map)
