The magnetic potential is implicitly defined as a field which satisfies

where 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.
