Struct Dipole 

pub struct Dipole {
    pub pos: Vec3,
    pub moment: Vec3,
}

Electric dipole: two equal and opposite charges separated by a small distance.

Fields

pos: Vec3

moment: Vec3

Implementations

impl Dipole

pub fn new(pos: Vec3, moment: Vec3) -> Self

pub fn field_at(&self, point: Vec3) -> Vec3

Electric field of a dipole at a given position (far-field approximation). E = (1/4pieps0) * [3(p·r_hat)r_hat - p] / r^3

pub fn potential_at(&self, point: Vec3) -> f32

Electric potential of a dipole at a given position. V = (1/4pieps0) * p·r_hat / r^2

pub fn to_charges(&self, separation: f32) -> [PointCharge; 2]

Convert dipole to a pair of point charges for exact computation.
