magnetization – מילון אנגלי-אנגלי
magnetization (Amer.)
n.
act of magnetizing, impartation of magnetic properties upon an object (also magnetisation)
Magnetization
In
classical electromagnetism,
magnetization (
magnetisation in British English) or
magnetic polarization is the
vector field that expresses the
density of permanent or induced
magnetic dipole moments in a magnetic material. The origin of the magnetic moments responsible for magnetization can be either microscopic
electric currents resulting from the motion of
electrons in
atoms, or the
spin of the electrons or the nuclei. Net magnetization results from the response of a material to an external
magnetic field, together with any unbalanced magnetic dipole moments that may be inherent in the material itself; for example, in
ferromagnets. Magnetization is not always uniform within a body, but rather
varies between different points. Magnetization also describes how a material responds to an applied
magnetic field as well as the way the material changes the magnetic field, and can be used to calculate the
forces that result from those interactions. It can be compared to
electric polarization, which is the measure of the corresponding response of a material to an
electric field in
electrostatics. Physicists and engineers define magnetization as the quantity of
magnetic moment per unit volume. It is represented by a vector M.

About
Magnetization
Magnetization Influences which one person may exercise on another akin to mesmerism whether of a gross physical nature, to which the term animal magnetism is applied, or of a loftier nature, the action of mind upon mind. Metallic magnetism is itself one manifestation of subtle natural forces, of which personal magnetism is another manifestation. Magnetism, whether diffuse or localized or in the form of animal magnetism, is an emanation from the beings which produce it from their own inner vital power, and hence magnetism is a fluid. Those who are especially endowed with the faculty of arousing it in themselves and projecting it, mainly through the tips of the fingers or the eyes, can use it for either corrective, or for evil and destructive, purposes; while all other beings, even inanimate objects, possess it but do not emanate it willfully or consciously. It flows forth from them as an aura, usually unconsciously. Thus magnetism has an auric efflux or fluid, which finds its foundation in the vitality or pranic sources of the beings or things from which it flows.
