Table P30.70 contains data taken for a ferromagnetic material.
(a) Construct a magnetization curve from the data. Remember that B = B0 + μ0M.
(b) Determine the ratio B/B0 for each pair of values of B and B0, and construct a graph of B/B0 versus B0. (The fraction B/B0 is called the relative permeability, and it is a measure of the induced magnetic field.) |
