MagneticFieldStrength¶

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

Specifies the magnetic field strength, $\VField{H}$ , also called magnetic field or magnetic field intensity. Units are ampere per meter, $\units{A/m}.$

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

# define a constant magnetic field strength
MagneticFieldStrength = [..., ... , ...]

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

# define an magnetic field strength as a section
MagneticFieldStrength {
  PlaneWave {...}
  Python {...}
  ...
}

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

Note

Setting a magnetic field strength will implicitly define a consistent electric field as follows from Maxwell’s equations whenever the electric field is not explicitly specified. Conversely, setting a electric field will yield a magnetic field, when not specified otherwise.
