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?

"normal" determination to estimate permeability I'm working on a magnetic circuit using a cast steel rectangular core with a .0008m air gap. There is a hint the question that says, 'Use a "normal" determination to estimate μ from the graph.' What exactly is a "normal" determination...

really dough brain? how is this different than you and your friends getting together to work on assignments?

Homework Statement Electrons are accelerated between points A and B to the energy of 7.1keV, see attachment. The coordinate system was selected to have the origin at the startup point A. The electrons enter an area between two parallel plates where the magnetic field is established by...
