Reference no: EM13542472

Cobalt has a saturation magnetization of 1.4 times 106 A/m, and an atomic volume of 6.7 cm3/mole. (a) What is the magnetic dipole moment of each cobalt atom in Bohr magnetons? (b) You apply a magnetic field in the easy direction with a coil of 10 turns per meter carrying a current of 0.3 milliamps, and determine that the total field B within the sample is one tesla. Calculate M and determine what percentage of the volume now consists of domains with magnetization parallel to the field.
