Struct MagneticField 

pub struct MagneticField {
    pub flux_density: f64,
}

A simple magnetic field described by flux density.

Fields

flux_density: f64

Implementations

impl MagneticField

pub fn new(flux_density: f64) -> Option<MagneticField>

Creates a new magnetic field from flux density.

pub fn flux_through_area(&self, area: f64, angle_radians: f64) -> Option<f64>

Computes the magnetic flux through an area in this field.

pub fn force_on_charge( &self, charge: f64, velocity: f64, angle_radians: f64, ) -> Option<f64>

Computes the magnetic force on a moving charge in this field.

Examples

use std::f64::consts::FRAC_PI_2;

use use_magnetism::MagneticField;

let field = MagneticField::new(3.0).unwrap();
assert_eq!(field.force_on_charge(1.0, 2.0, FRAC_PI_2), Some(6.0));

pub fn force_on_wire( &self, current: f64, length: f64, angle_radians: f64, ) -> Option<f64>

Computes the magnetic force on a current-carrying wire in this field.

pub fn energy_density(&self) -> Option<f64>

Computes the magnetic energy density for this field.

Trait Implementations

impl Clone for MagneticField

fn clone(&self) -> MagneticField

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MagneticField

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for MagneticField

fn eq(&self, other: &MagneticField) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
