magnetic moment

Etymology: Gk, magnesia, lodestone, momentum, movement
a measure of the net magnetic field produced by an elementary particle or an atomic nucleus spinning about its own axis. Such fields are similar to the field surrounding a bar magnet and are the basis for magnetic resonance imaging.

magnetic moment

An MRI term for a measure of the net magnetic properties of an object or particle, which is a sum of the intrinsic spins of the nuclei that have an associated magnetic dipole moment interacting with a magnetic field.

magnetic moment,

n the twisting force experienced by a magnet located inside a magnetic field.

The electronic spectrum of Co (II) exhibits two bands at 14500 and 22000 cm-1 which may be assigned to the transitions 4T1g(F) - 4T1g(P) and 4T1g(F) - 4A2g(F), corresponding to an octahedral geometry, also supported by its magnetic moment value (3.
Magnetic moment is a measure of an object's intrinsic magnetism and also of the strength of its response to a magnetic field imposed from outside.
There are oxides that can sustain this type of excitation but with charge rather than magnetic moments, so the program is open to other approaches.
Our experiment has shown, based on a measurement six times more precise than any done before, that the standard model holds up, and that there seems in fact to be no difference in the proton/antiproton magnetic moments at the achieved measurement uncertainty.
For ferrites this magnetic moment is the difference between A and B sites.
The cell magnetic moment is increased in this way, because it is the sum of the individual moments of each magnetite crystal.
One such property is the magnetic moment, which describes how a particle responds to a magnetic field.
For the study of magnetism, the most important information obtained from Mossbauer spectra is hyperfine fields, which are magnetic fields acting on the nuclei and are closely related to the local magnetic moments of 3d electron spins.
In antiferromagnetism, the atoms within an object have opposite magnetic moments and cancel each other out, which makes them line up in orderly patterns.
This observation means that the electric and magnetic moments are proportional to I:
The total resultant field generated by neuronal activity will make a contribution to the phase of the processing magnetic moments within the sample, which is what MRI actually detects.
These magnetic moments are consistent with five coordinate square pyramidal geometry (Aliyu and Nwabueze, 2007; Craige, 2004).
