How hysteresis loss increases with frequency?
How hysteresis loss increases with frequency?
(OP)
Hi folks,
Everybody knows that hysteresis loss increases when frequency also increases.
This phenomenon is normally shown as an enlargement of the hysteresis area.
Is it true? I mean, will the histeresis become really "fat"?

Thank you for providing the link.
My doubt is:
physically, if the frequency increases, will the hysteresis area really "increase" or is this "increassing" only an "equivalent area" to represent the loss?
I am not a "magnetic man". My guess is that the hysteresis area is a characteristic of the material and the losses increase due to the increasing of the magnetic domains motions.
In other words, if the frequency doubles, the domains will duplicate their motions, with the hysteresis being "performed" twice. In this case the losses may be "equivalent" to a hysteresis with twice the area.
If the hysteresis bacomes really "fat" then the material characteristics will change, I think.

It is the increased coercivity that makes the hysteresis loop look "fat".
