Homework Help: How to find the normal approximation of B for cast iron from the B-H curve?

  1. Sep 29, 2011 #1
    I need to know how to find the normal approximation of B for cast iron from the B-H curve.

    I know for sheet steel, I can use a B of 1 and get 400 for H and use B=μH to get 0.0025 Wb/At-m.

    How is it done for cast iron?

    Have you tried searching for magnetization curves on google? Flip through this online book, there are some neat graphs on page 152: "ttp://books.google.com.au/books?id=SPEQGU9u4mMC&pg=PA150&lpg=PA150"[/URL]
