Effect of the creep exponent on flux density distribution

Effect of the creep exponent: Flux density distribution

The blue background on the plots correspond to the strip area, while regions outside the strip are black.

Distinctions:

For weak creep, after field reversal there is a definite position of the flux front separating immobile flux in the central area and moving flux in the rest of the strip. For strong creep the flux front position is vague.
For strong creep an enhanced gradient of flux density is found where B = 0.
