    A good bar magnet may have a magnetic moment of magnitude 0.1 Am 2 and a volume of 1 cm 3, or 1215;10 6 m 3, and therefore an average magnetization magnitude is 100,000 A/m. Iron can have a magnetization of around a million amperes per meter. Such a large value explains why iron magnets are so effective at producing magnetic fields.
