A sinusoidal current carrying conductor is surrounded by nonlinear ferromagnetic core.
Problem Type:
A planeparallel problem of nonlinear AC magnetics.
Geometry:
Given:
Total current I = 500 A.
Frequency f = 50 Hz.
Core BHcurve: H = 100·B^{2}
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 Formulations in AC Magnetics).
In this particular case the modified BHcurve can be calculated as B`(H) = B(H) * (1 + 1/sqrt(180))
