Magnetic-field intensity

The sensibility to defects and other testing parameters of pieces can be modified by the geometry of the piece to be controlled and the conception of the probe. It is sufficient to set the direction of circulation of eddy currents, regulate the magnetic field intensity and choose the coil of the appropriate size. 

The intensity of the magnetic field H is measured in amperes per meter. For a single-laver solenoid, at anv point along its axis the magnetic field intensity is... 

Flux density is calculated as the permeability of free space times the sum of the magnetic-field intensity and the induced magnetization... 

The magnetic susceptibility of a material (%, volume susceptibility) is dimensionless and is defined as the ratio of induced magnetization to magnetic field intensity. It is expressed as... 

H = magnetic-field intensity dB/dz = magnetic-field gradient T = fluid viscosity b = particle diameter... 

Separations similar to those obtained with dry induced-roll devices can be obtained with cross-belt separators (Fig. 19-42). These units are built with up to eight poles, each of which can operate at different magnetic-field intensities to allow simultaneous production of different concentrates. However, capacity is low, and installed costs per ton capacity are high compared with induced-roll units. 

These fluctuations will affect the motion of charged particles. A major part of the Lamb shift in a hydrogen atom can be understood as the contribution to the energy from the interaction of the electron with these zero point oscillations of the electromagnetic field. The qualitative explanation runs as follows the mean square of the electric and magnetic field intensities in the vacuum state is equal to...

Scientists measure many different quantities—length, volume, mass (weight), electric current, temperature, pressure, force, magnetic field intensity, radioactivity, and many others. The metric system and its recent extension, Systeme International d Unites (SI), were devised to make measurements and calculations as simple as possible. In this chapter, length, area, volume, and mass will be introduced. Temperature will be introduced in Sec. 2.7 and used extensively in Chap. 11. The quantities to be discussed here are presented in Table 2-1. Their units, abbreviations of the quantities and units, and the legal standards for the quantities are also included.

From the knowledge of the spectrometer s operating frequency (held constant) and the magnetic field intensity at which maximum EPR absorption occurs as one varies the magnetic field, one easily calculates g from equation 3.17. 

B is the magnetic field intensity, r is the radius of the ion path, and V is the accelerating potential. In analytical mass spectrometers either B or V is varied systematically so that ions of different m/z are sequentially focused on the collector and the spectrum recorded. Such whole molecule mass spectrometers have been employed occasionally for isotope ratio measurements but their use is restricted to samples... 

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. 

Now we write the same Fourier of expansion for the electric field and write everything according to the magnetic field intensity H = B, and we find with the case that (e/H)Aq co the amplitude fixed to the wavelength as is the case for some solitons, for Gaussian packets, we arrive at the same cubic Schrodinger equation ...
