Physics.Learn.Current

Description

This module contains functions for working with current, magnetic field, and magnetic flux.

Synopsis

# Current

type Current = Double Source #

Electric current, in units of Amperes (A)

A current distribution is a line current (current through a wire), a surface current, a volume current, or a combination of these. The VectorField describes a surface current density or a volume current density.

Constructors

 LineCurrent Current Curve current through a wire SurfaceCurrent VectorField Surface VectorField is surface current density (A/m) VolumeCurrent VectorField Volume VectorField is volume current density (A/m^2) MultipleCurrents [CurrentDistribution] combination of current distributions

# Magnetic Field

The magnetic field produced by a current distribution. This is the simplest way to find the magnetic field, because it works for any current distribution (line, surface, volume, or combination).

Arguments

 :: Current current (in Amps) -> Curve geometry of the line current -> VectorField magnetic field (in Tesla)

Magnetic field produced by a line current (current through a wire). The function bField calls this function to evaluate the magnetic field produced by a line current.

Arguments

 :: VectorField surface current density -> Surface geometry of the surface current -> VectorField magnetic field (in T)

Magnetic field produced by a surface current. The function bField calls this function to evaluate the magnetic field produced by a surface current. This function assumes that surface current density will be specified parallel to the surface, and does not check if that is true.

Arguments

 :: VectorField volume current density -> Volume geometry of the volume current -> VectorField magnetic field (in T)

Magnetic field produced by a volume current. The function bField calls this function to evaluate the magnetic field produced by a volume current.

# Magnetic Flux

The magnetic flux through a surface produced by a current distribution.
