Bijli — Electromagnetism Simulation

Hindi: बिजली (bijli) — electricity, lightning

Electromagnetism simulation for the AGNOS ecosystem. Electric and magnetic fields, Maxwell's equations, charge dynamics, and EM wave propagation.

Built on hisab for PDE solvers and impetus for particle interactions.

Quick Start

use bijli::field;
use bijli::charge::{self, PointCharge};
use bijli::maxwell;

// Electric field from a point charge
let e = field::electric_field_point_charge(1e-6, [0.0; 3], [1.0, 0.0, 0.0]).unwrap();

// Coulomb force
let q1 = PointCharge::proton([0.0; 3]);
let q2 = PointCharge::electron([5.3e-11, 0.0, 0.0]);
let f = charge::coulomb_force(&q1, &q2).unwrap();

// Speed of light from Maxwell's equations
let c = maxwell::wave_speed(field::EPSILON_0, field::MU_0).unwrap();
