Magnetic field intensity Effective

With most lines, however, ail anomalous Zeeman effect is observed and the number of components is greater, in some cases reaching twelve or fifteen. They are symmetrically arranged and symmetrically polarized. The displacements, as in the simpler case, are proportional to the magnetic field intensity H, and are always e xpressible, in wave numbers, as rational multiples of the displacement in the normal effect, which is 4.67 x 10 5H (reciprocal centimeter), a quantity known as the Loientz unit. The Zeeman effects observed in sun spots give valuable information as to the magnetic conditions in those areas.

A second possible cause of spurious ringing which is limited only to some solids is piezoelectric resonance of the sample. (Of course the cause need not be limited to a sample. More on this later.) A piezoelectric crystal has the property that a mechanical deformation of the material takes place in the presence of an electric field. Therefore, an acoustic ringing can be induced in a piezoelectric material located within an NMR probe by the rf electric field associated with the rf magnetic field. Such a ringing due to piezoelectricity has the distinguishing property that it is independent of the applied magnetic field intensity in contrast with the magnetic field induced effect described in the first part of this section. 

By the figures we can know, the surface tension of water continue lower when the magnetic field intensity is between 0.5-0.7T, at the same time, the water is more easy moist coal and spray dust the water-coal contact corner is linear decrease when the magnetic field intensity is between 0.6-1.2T and the law is obvious the water-coal contact corner is reach for the minimum number 29.2 when the magnetic field intensity is 1.2T, that is reduced by half and has obviously effects. 

The magnetic field also widens the temperature-concentration region of the existence of the LC phase. This effect is related to the cholesteric liquid crystal - nematic liquid crystal phase transition and the orientation of macromolecules in the direction parallel to the magnetic field lines. In this case, large supramolecular structures (domains) develop in solutions. The effect of magnetic field on the variation in LC transitions with the pwlymer concentration in solution shows an extremal pattern. Figures 15 and 16 demonstrate the concentration dependences of AT for HPCl- DMAA, HPC-3-DMAA, and HPC-l-water systems measured at various magnetic field intensities. 

The effect of the magnetic field (intensity Hq) on the spontaneous curvature Cq is due to the modification it implies on the particles concentration profile in the vicinity of the bilayer. Qualitatively the depletion in nanoparticles is reduced near the magnetic poles because of magnetic attraction. The effect of this phenomenon on Cq can be quantitatively described by introducing an angular dependence in the expression of the decay factor of the electrostatic potential away from the bilayer ... 

Figure 5.20 shows the effect of magnetic field intensity on the dependence of A/i on the polymer concentration. 

Other position measurement devices utilize different electrical properties that can be used for position measurements, such as capacitance and magnetic field intensity (Hall effect).
