What is the state of electrons at the surface of a neutron star? Group of answer choices The electrons have all merged with the protons to form neutrons. The electrons are bound to iron nuclei left over from the supernova. The electrons form a degenerate fermi gas that suffuses the surface lattice. The electrons are ejected in the neutron star jets.

Ising model of Ferromagnets

The Ising model is one of the easiest and most famous theoretical models for ferromagnetism in statistical mechanics. When a group of atomic spins aligns such that their magnetic moments are pointed in the same direction and produce a strong permanent magnetic moment in macroscopic size, the phenomenon is called ferromagnetism. The relative permeability of these magnets is greater than unity and increasing magnetization with the applied external field. Even in the absence of an external magnetic field, these substances retain spontaneous magnetization. An example of ferromagnets is iron.
