... polarity (like little magnets). Atoms tend to line up parallel to each other within domains of the material. A magnetic field can force the domains to line up, and the material itself can become magnetic. (Ex: iron, nickel, cobalt, steel) Paramagnetic materials are weakly attracted to magnets. The a ...

... For all practical purposes, however, µr = 1 for optical frequencies Magnetic fields inside magnetic materials polarize the material, meaning that the vector sum of magnetic dipoles inside the material is no longer zero. The decisive quantities are the magnetic dipole moment m, a vector, and the magn ...

Magnetism - District 196
... We now know today that magneic fields are produced by the motion of electric charges. The charges can spin or orbit. Electrons have two magnetic fields, one due to the spin and one due to its orbit about the nucleus. The field due to the spin is stronger. In most materials the spins of the electrons ...
