Magnetic induction density

Magnetic flux density (magnetic induction) gauss G, Gs 10-4T... 

The SI unit for magnetic flux density or magnetic induction (symbolized by T) equal to a weber per square meter. One tesla is equivalent to lO" gauss. 

The density (or flux) of the lines of force in a solid placed in a magnetic field (H) is termed the magnetic induction, B, and is given by the relationship. 

GAUSS (G). A unit of magnetic flux density, or magnetic induction. The ratio of the flux in any cross section to the area of that cross section, the cross section being taken normal to the direction of flow. One gauss equals j maxwell per square centimeter. (The gauss is a unit of the CGS system. Use of the SI unit the tesla, is preferred.)... 

TESLA (T). A unit of magnetic flux density (magnetic induction). The magnetic flux density of a uniform field that produces a torque of 1 newton-meter on a plane current loop carrying 1 ampere and having a projected area of 1 square meter on the plane perpendicular to the field. T = N/A in. (The SI unit of magnetic flux density)... 

Various methods exist to accurately proportion syrup and water, though the most popular current system uses flow meters. The syrup is usually dosed though a mass flow meter and the water is dosed volumetrically using a magnetic induction flow meter. This allows for density variations within the syrup... 

One of many types of equipment variously claimed to control and prevent scaling or, in addition, to prevent corrosion or possibly even algae and sludge in water circuits by nonchemical means. Usually they employ external electrical circuits or permanent magnets to provide a magnetic induction (flux density) of perhaps 2500 gauss. Usually clamped around or inserted into a pipeline. 

In all our experiments the two magnetic bars are immersed in an external magnetic field. The intensity of the magnetic field is proportional to the density of force lines (Fig. 1.4). Later, we will be interested in the effective field in a given region of space, which is referred to as magnetic induction B (expressed in tesla) ... 

Fig. 11.5.4 Magnetic induction or flux density B as a function of the strength H of an external field.

The designation B (magnetic induction or flux density) supercedes H (magnetic intensity). The SI term tesla (7 ), the unit of measurement for B, supercedes the term gauss (G) T =104 G. The frequency term hertz (Hz) supercedes cycles per second (cps). MHz is megahertz (106 Hz). 

Equation (1-10) applies both to the case of a molecule in vacuo and in solution. The (polarizable) environment makes contributions both through the density matrix, which is obtained self-consistently including the perturbation from the surroundings, and through the derivative of the density matrix with respect to the magnetic induction, i.e., both terms in Eq. (1-10) contain the effect of the environment. 

The first derivative of the density matrix with respect to the magnetic induction (dPfiv/dBi) is obtained by solving the coupled-perturbed Hartree-Fock (or Kohn-Sham) equations to which the first derivative of the effective Fock (or Kohn-Sham) operator with respect to the magnetic induction contributes. Due to the use of GIAOs, specific corrections arising from the effective operator Hcnv describing the environment effects will appear. We refer to Ref. [28] for the PCM model and to Ref. [29] for the DPM within either a HF or DFT description of the solute molecule. 

Since magnetic monopoles have never been found, the irreducible magnetic entity must be the magnetic dipole. In Ampere s law, we can define the magnetic flux density or magnetic induction B due to, or induced by, an electrical current j at a distance r, as... 

Table G Definitions of the Electric Field E, the (Di)electric Polarization P, the Electric Displacement D, the Magnetic Field H, the Magnetization M, the Magnetic induction or flux density B, statement of the Maxwell equations, and of the Lorentz Force Equation in Various Systems of Units rat. = rationalized (no 477-), unrat. = the explicit factor 477- is used in the definition of dielectric polarization and magnetization c = speed of light) (using SI values for e, me, h, c) [J.D. Jackson, Classical Electrodynamics, 3rd edition, Wiley, New York, 1999.]. For Hartree atomic u nits of mag netism, two conventions exist (1) the "Gauss" or wave convention, which requires that E and H have the same magnitude for electromagnetic waves in vacuo (2) the Lorentz convention, which derives the magnetic field from the Lorentz force equation the ratio between these two sets of units is the Sommerfeld fine-structure constant a = 1/137.0359895...
