}

A source of electric / magnetic field.

Variants

Uniform

Uniform vector electric or magnetic field.

Fields

electric: Vec3Fix

Uniform electric field E (V/m).

magnetic: Vec3Fix

Uniform magnetic field B (T).

PointCharge

Point charge at position with strength charge_c, producing an inverse-square Coulomb field E = k · q / r² · r̂ with k = 8.99e9 V·m/C.

Fields

position: Vec3Fix

World-space position of the source.

charge_c: Fix128

Charge in coulombs.

MagneticDipole

Ideal magnetic dipole with moment m at position. Produces B = μ₀ / (4π) · (3(m·r̂)r̂ − m) / r³ with μ₀ / (4π) ≈ 1e-7 T·m/A.

Fields

position: Vec3Fix

World-space position of the dipole.

moment: Vec3Fix

Dipole moment vector m (A·m²).
