Magnetic susceptibility corresponds to the internal magnetization of a tissue resulting from the interactions with an external magnetic field. When two tissues with different magnetic susceptibilities are juxtaposed, it causes local distortions in the magnetic field.

Susceptibility is a measure of the extent to which a substance becomes magnetized when it is placed in an external magnetic field. A synonym for susceptibility is magnetizability when matter interacts with the magnetic field, an internal magnetization or polarization (j) is created that either opposes or augments the external field.
Simply put, magnetic energy is the energy that operates within a magnetic field. A magnetic field is invisible to the naked eye, but that does mean that the effects of magnetic energy are not felt.
Iron deposition can be identified qualitatively at chemical shift imaging by magnetic susceptibility–related signal intensity loss on the longer te in-phase images or can be assessed both more sensitively and quantitatively by using a multigradient-echo technique with an empirically derived relationship between the calculated relaxation.

Beleive it or not, there are actually many things you can get magnet wire from. What is magnet wire? magnet wire is a thin (usually around 20-30 awg) wire that is used to pass electricity through to produce a magne.
Clinical magnetic resonance imaging (mri) studies report changes of susceptibilities and relaxation rates in various neurological diseases which are often equated with changes in regional brain iron content. However, these mentioned metrics lack specificity for iron, since they are also influenced by the presence of myelin.
The most important class of magnetic materials is the ferromagnets: iron, nickel, cobalt and manganese, or their compounds (and a few more exotic ones as well). The magnetization curve looks very different to that of a diamagnetic or paramagnetic material.

The magnetic susceptibility of igneous rocks depends on the temperature, pressure, and composition of the parent magma. These parameters determine the abundance and type of iron-bearing minerals which are present once the magma has cooled. In general, felsic igneous rocks are characterized as having a lower iron content than mafic rocks.

A compound with respect to whose frequency the chemical shifts of other compounds can be compared. The standard can be either internal or external to the sample. Because of the need for possible corrections due to differential magnetic susceptibility between an external standard and the sample being measured, the use of an internal standard is generally preferred.
