Lodestone is a colletion of packages to calculate magnetic fields of any object or objects in 2D and 3D; along with any induced forces and torques. This consists of:

• lodestone_core a Rust library for handling all calculations and file parsing
• lodestone_python a planned wrapper to expose lodestone_core as a native module in Python
• magnet_rs a command line tool to calculate

This is a rewrite of a Python package pymagnet: Github, or PyPi.

This code uses analytical expressions to calculate the magnetic field due to simple magnets. These include:

• 2D: rectangles, squares, arbitrary polygons
• 3D: cuboids, cylinders, solenoids, spheres, arbitrary polyhedra
