Unformatted text preview: what type(s) of magnetism would you suggest as being displayed by this material? Why? 7. Assume there exists some hypothetical metal that exhibits ferromagnetic behavior and that has (1) a simple cubic crystal structure, (2) an atomic radius of 0.125 nm, and (3) a saturation flux density of 0.85 tesla. Determine the number of Bohr magnetons per atom for this material. Grading: 10 points each....
