Answer is in units of nm. Answer in decimal form.Iron has a magnetic moment of 2.22 Bohr magnetons per atom and a density of 7.87-103 kg.m-3. Calculate the expected magnetization of iron at 0 K and describe any assumptions that you have made. How would you expect this magnetization of iron to vary as temperature is increased. How does the number of Bohr magnetons per atom change from 0 K to 300 K. Why does a piece of iron typically not exhibit high magnetization at room temperature (unless it has been "magnetized")?
