analyze-magnetic-field SKILL.md skillA
analyze-magnetic-field from pjt222/agent-almanac is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add pjt222/agent-almanac/analyze-magnetic-field@v1.0Pins v1.0 in mdr.lock. Pin the fingerprint instead.

Calculate and visualize magnetic fields produced by current distributions using the Biot-Savart law, Ampere's law, and magnetic dipole approximations. Use when computing B-fields from arbitrary current geometries, exploiting symmetry with Ampere's law, analyzing superposition of multiple sources, or characterizing magnetic materials through permeability, B-H curves, and hysteresis behavior.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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) …

How to install
mdr add pjt222/agent-almanac/analyze-magnetic-field@sha256:e98aa7a8c0dcbd5dThe line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
