Problem 7 MT: Field intensity vs. penetration depth (8 points) The formula for the field intensity, measured from the surface of a cylindrical bar carrying alternating current is given by where d is the depth / is the AC frequency, μ is the magnetic permeability, and σ is the electrical conductivity. Compute the variation of H with depth for a 2 cm diameter steel bar of average relative permeability 500, with a 30 Oe surface field strength. You can assume power comes directly from a standard U.S. wall outlet. Use a B-H curve to plot the variation of B as a function of depth
