HMagn3: nonlinear ferromagnetic core in sinusoidal magnetic field

A sinusoidal current carrying conductor is surrounded by nonlinear ferromagnetic core.

Problem Type:

Plane problem of AC magnetics.

Geometry:

Given:

Total current I = 500 A.
Frequency f = 50 Hz.
Core BH-curve: H = 100·B2

Problem:

Calculate B and H distribution along the radius r.

Results:

To calculate the sinusoidal filed distribution in nonlinear core we should use the modified curve B'(H) (see more in QuickField documentation).
In this particular case the modified BH-curve can be calculated as B`(H) = B(H) * (1 + 1/sqrt(180))
