isotropic

Magnetic induction, like other fluxes such as electrical, thermal or fluid currents, is defined with reference to an area; it satisfies the same conditions of continuity as the electric current does, and in isotropic media it depends on the magnetic force just as the electric current depends on the electromotive force.

12The polarization itself is determined from the electric force (P,Q,R) by the usual statical formula of linear type which becomes tor an isotropic medium (.f',g',h') = c2(P,Q,R), because any change of the dielectric constant K arising from the convection of the material through the aether must be independent of the sign of v and therefore be of the second order.

00Other names for the circular lines are " circulars " or " isotropic lines."

00biaxial compression of an isotropic skin with fiber reinforced integral unflanged stiffeners.

00One possibility is to assume isotropic sky conditions at all times and so simplify computation since diffuse radiation is then independent of direction.

00cosmic ray flux, which would otherwise be isotropic, is shaped by the Earth's magnetic field.

00cosmology page 1 This does not mean the universe seems isotropic to every possible observer.

00Isotropic etchants attack the material equally in all directions and anisotropic etchants attack the material at different rates in different directions.

00But the incoming cosmic ray flux, which would otherwise be isotropic, is shaped by the Earth's magnetic field.

00This is because the glass is optically isotropic, and does not change the polarization state of the light passing tho it.

00A standard dipole radiation pattern is not isotropic - it looks bit like a donut with the antenna in place of the hole.

00This is nothing at all like our nearly isotropic and homogeneous universe, where each point has a different event horizon.

00CTE is not necessarily isotropic, that is, the same in all directions.

00The emission of most radionuclide neutron sources is not isotropic.

00remanent moments are found to be associated with a more isotropic reversal mechanism.

00Lehmann it melts at 168Ã‚° (or at a slightly lower temperature in its water of crystallization) and on cooling forms optically isotropic crystals; at 125.6Ã‚° the mass becomes doubly refracting, and from a solution rhombohedral (optically uniaxial) crystals are deposited; by further cooling acicular rhombic crystals are produced at 82.8Ã‚°, and at 32.4Ã‚° other rhombic forms are obtained, identical with the product obtained by crystallizing at ordinary temperatures.

00electromagnetic system of units will be generally adopted, and, unless otherwise stated, magnetic substances will be assumed to be isotropic, or to have the same physical properties in all directions.

00Magnetic induction, like other fluxes such as electrical, thermal or fluid currents, is defined with reference to an area; it satisfies the same conditions of continuity as the electric current does, and in isotropic media it depends on the magnetic force just as the electric current depends on the electromotive force.

00Hence if the induction per square centimetre at any point is denoted by B, then in empty space B is numerically equal to H; moreover in isotropic media both have the same direction, and for these reasons it is often said that in empty space (and practically in air and other nonmagnetic substances) B and H are identical.

00The small magnet may be a sphere rigidly magnetized in the direction of Ho; if this is replaced by an isotropic sphere inductively magnetized by the field, then, for a displacement so small that the magnetization of the sphere may be regarded as unchanged, we shall have dW = - vIdHo = v I+-, whence W = - 2 I + H2 Ã‚° (37) The mechanical force acting on the sphere in the direction of displacement x is 1 Hopkinson specified the retentiveness by the numerical value of the " residual induction " (=47rI).

00So long as the wire (supposed isotropic) is free from torsional stress, there will be no external evidence of magnetism.

00The curve showing the circumferential (or longitudinal) changes was also plotted, and from the two curves thus obtained it was easy, on the assumption that the metal was isotropic in directions at right angles to the magnetization, to calculate changes of volume; for if circumferential elongation be denoted by 1 1, and transverse elongation by 1 2, then the cubical dilatation (40r -) = l l 2/ 2 approximately.

00The experimental results agreed in sign though not in magnitude with those calculated from the changes produced by simple longitudinal magnetization, discrepancies being partly accounted for by the fact that the metals employed were not actually isotropic. Heusler's alloy has been tested for change of length by L.

00The polarization itself is determined from the electric force (P,Q,R) by the usual statical formula of linear type which becomes tor an isotropic medium (.f',g',h') = c2(P,Q,R), because any change of the dielectric constant K arising from the convection of the material through the aether must be independent of the sign of v and therefore be of the second order.
