In the so-called "Delta E effect," it is induced by elastic tension, and the Fleming-Kennelly law states that the reluctivity of a substance with this property varies linearly with field strength at certain points. Heisenberg's theory of it assumes that parallel electron spins are favored and Ewing's theory of it assumes that each atom can turn freely about its center, though Weiss's theory is more generally accepted today. Characterized by a transition temperature called the Curie temperature, it is caused when an external field aligns microscopic regions, or domains. For 10 points, what is this form of magnetism possessed by iron?
