For an atom, the mean value of Σ <r2> is about 10−21squaremetreand χmolehasvaluesof 10−9to 10−10; theatomic numberZequals the number of electrons in each atom. The quantity Σ <r2> for each atom, and therefore the diamagnetic susceptibility, is essentially independent oftemperat...

The meaning of MAGNETIC POTENTIAL is the scalar quantity characteristic of a point in a magnetic field whose negative gradient equals the intensity or strength of the magnetic field and which represents the work required to bring a unit north pole from a
The quantity represents the rate at which the direction of local magnetization rotates with position in the wall (Cullity and Graham, 2009). 3.3 Magnetostatic or Demagnetization Energy The magnetized material behaves like a magnet, with a surrounding magnetic field. This field acts to magnetize the...
Magnetic susceptibility is defined as a thermodynamic quantity that involves the partial differentiation of magnetization with respect to the applied field. It can vary from the mean magnetic susceptibility when the behavior of the magnetic material is nonlinear. ...
More specifically, for a given phonon q the root-mean-square (RMS) of the time dependence of the periodic part of this quantity reflects the overall amplitude of the spin–density associated to a single phonon mode. For each cartesian component α we have (see Supplementary Note 2): $$\...
S5). To only reflect the response of the external field to microrobot interactions, we selected the characteristic quantity \({m}_{0}{H}_{0}\) to represent the torque; where \({H}_{0}\) is the modulus of the applied external magnetic field, \({m}_{0}=4\pi {\mu }_{0}{a}...
The magnetic field strength created by an electric current can be calculated from the Biot-Savart law or from Ampère’s law [55,56]. In the SI unit system the strength of magnetic field, H is measured in amperes per metre (A/m) which indicates the relation of this quantity to the ...
However, the same formulation also applies to diffusion MRI37, where application is simpler due to the availability of the [Math Processing Error]b=0 data point, where b is the conventional symbol for the combination of gradient strengths and timing that defines diffusion sensitization. In this ...
