Here's the question you clicked on:

Shouldn't the hysteresis loop be symmetric with respect to the origin always? Why isn't that happening? Even with non-ideality whatever you get with +ve H should be true with -ve H also, right?
I mean the Magnetic hysteresis loop for a material.
Depends on your function and what the axes represent... The critical thing when discussing these is knowing either it's internal state or it's history. Related reading: http://openstudy.com/users/cshalvey#/updates/5006f70ee4b020a2b3bc8932
Thanks for the link, but it isn't related to my question! http://en.wikipedia.org/wiki/Hysteresis#Magnetic_hysteresis If I take the hysterisis loop of say, soft iron kept within a solenoid, then the variation in H indicates the variation in current ( I ) . So, if I start with current in positive direction, or negative how does it really matter? It should give the same result, right?
