Description

pict

This component models a segment of a magnetic core. It establishes a linear relationship between the magnetic flux P   and the magneto-motive force F  

P   μ μ A
--= -0-r--
F      l

where μ0 = 4π × 10-7N∕A2   is the magnetic constant, μr   is the relative permeability of the material, A   is the cross-sectional area and l   the length of the flux path.

Parameters

Cross-sectional area
Cross-sectional area A   of the flux path, in  2
m  .
Length of flux path
Length l   of the flux path, in m.
Rel. permeability
Relative permeability μr   of the core material.
Initial MMF
Magneto-motive force at simulation start, in ampere-turns (A).

Probe Signals

MMF
The magneto-motive force measured from the marked to the unmarked terminal, in ampere-turns (A).
Flux
The magnetic flux flowing through the component, in webers (Wb). A flux entering at the marked terminal is counted as positive.
Field strength
The magnetic field strength H   in the core element, in A/m.
Flux density
The magnetic flux density B   in the core element, in teslas (T).
