i have been on this question all day reading and searching on line but i am not sure how to answer it. every article on the relationship of B/H immediately goes into equations and does not explain anything .
all i can think to say is that with cast iron the flux density increases fast to 0.5 at a field strength of 2000 at/m the flux density then gradually increases at a slower rate to a maximum of 0.9 at the field strength goe from 20 at/m to 8000at/m .
Q- Using the above graph, comment on how the material affects the B-H relationship for cast iron and mild steel.
