Magnetization

Magnetization main The magnetization vector field M represents how strongly a region of material is magnetized.

Thermoremanent magnetization on Earth gives iron minerals formed in the Earth’s crust, a higher magnetization than if they were formed in the same field at room temperature.

This model clarifies the connection between angular momentum and magnetic moment, which is the basis of the Einstein–de Haas effect rotation by magnetization and its inverse, the Barnett effect or magnetization by rotation.

Time dependence of the magnetization There is no time-dependence of the magnetization when the nanoparticles are either completely blocked ( ) or completely superparamagnetic ( ).

The objective of 23R-001 (Figure 3) is to test a TMI magnetic low associated with a zone of high magnetization, coinciding with a strong chargeability anomaly.

This led Krawczynski and the other scientists to think the cause for magnetization being caused by something local.

This magnetization switching was accomplished without a magnetic field while preserving the conventional properties of SrRuO used in previous studies.

In the paramagnetic state, the local thermal fluctuations of magnetization (i.e. paramagnons) form little packets of magnons.

A good permanent magnet can have a magnetization as large as a million amperes per meter.

An antiferromagnet has two networks of equal and opposite magnetic moments, which cancel each other out so that the net magnetization is zero.

By adding a " magnetic core " made of a ferromagnetic material like iron inside the coil, the magnetizing field from the coil will induce magnetization in the material, increasing the magnetic flux.

Closer to the magnet, the magnetic field becomes more complicated and more dependent on the detailed shape and magnetization of the magnet.

Diamagnetics are defined by the generation of a spontaneous magnetization of a material which directly opposes the direction of an applied field.

During manufacture the materials are subjected to various metallurgical processes in a powerful magnetic field, which aligns the crystal grains so their "easy" axes of magnetization all point in the same direction.

Einstein–de Haas experiment main Einstein and De Haas demonstrated that magnetization is due to the motion of electrons, nowadays known to be the spin.

Energy stored in magnetic fields main seeAlso Energy is needed to generate a magnetic field both to work against the electric field that a changing magnetic field creates and to change the magnetization of any material within the magnetic field.

Even in the presence of the field there is only a small induced magnetization because only a small fraction of the spins will be oriented by the field.

Ferromagnetic materials seeAlso The table on the right lists a selection of ferromagnetic and ferrimagnetic compounds, along with the temperature above which they cease to exhibit spontaneous magnetization (see Curie temperature ).

History and distinction from ferrimagnetism Historically, the term ferromagnetism was used for any material that could exhibit spontaneous magnetization: a net magnetic moment in the absence of an external magnetic field.

However, an excessively strong magnetic field, whether alternating or constant, may mechanically deform (bend) the shadow mask, causing a permanent color distortion on the display which looks very similar to a magnetization effect.
