A cube of uniformly magnetized material of side length L = 0.050 m has magnetization M = 2000 amperes per meter when sitting on the table. You then place the cube in a uniform, upward pointing magnetic field of strength Bext = 0.0040T. The cube’s magnetization vector is also pointing upward. The magnetization remains at M = 2000 A/m. (a) From what we’ve said above, must the cube be made from a paramagnetic, diamagnetic, or ferromagnetic material? (b) When the cube is sitting in the external magnetic field, what is the strength of the magnetic field inside the cube? (c) When the cube is in the external field, how much work would it take to flip the cube over?
