Hysteresis loop

  1. Feb 7, 2005 #1

    At first, I think I have to make it clear to you that I suck at physics and my major in college is digital/media technology, and in Finland, we must have engineering physics passed to graduate. It's been over 2 years since I read physics and I still have those 'chapter 13' exercises undone. (what a coincidence that it's chapter '13')

    Anyway, I have particularly one exercise that's way too hard for me. It goes like this...

    'Prove that hysteresis loop's area unit is J/m3, which is energy per volume unit'

    I have no idea where to start and how to proceed. I'm more like a graphic designer not a physics laboratory assistant. I hope you still could help with this. I made a search and found one, but I'm not sure if it solves my problem, and I really didn't understand it.

    Thanks in advance...

    ...from Finland :confused:

    [tex][w]_{SI}=_{SI}\cdot[H]_{SI}=TA/m=\frac{N}{Am} \cdot \frac{A}{m}=\frac{N}{m^2}=\frac{J}{m^3}[/tex]

    ([tex]1 J=1 N \cdot m[/tex])
