MagneticPotential

Type:1-Tensor, or section
Range:[v_1, …, v_3]
Default:-/-
Appearance:optional

Specifies the magnetic potential \VField{A}. Units are \units{Wb/m=Vs/m}.

The magnetic potential is implicitly defined as a field which satisfies

\begin{eqnarray*} \VField{B} & = & \curl \VField{A}, \end{eqnarray*}

where \VField{B} is the magnetic flux density.

A constant magnetic potential can be defined by assigning a 3-vector:

# define a constant magnetic potential
MagneticPotential = [ ..., ..., ...]

For more general cases, a magnetic potential may be given as a section in order to deal with space, time, and parameter dependent definitions:

# define an magnetic potential as a section
MagneticFieldPotential {
  Constant {...}
  Python {...}
  ...
}

Field definitions within this section are summed up. Consult the subsequent sections to see which types of field definitions are allowed.
