CONSTITUTION:This thermally stable amorphous alloy having high magnetic flux density is represented by the formula (where T is Nb and/or Ta, preferably Nb, T' is Hf or Hf and Zr, preferably Hf, X=84-92% by atom, Y+Z=8-16%, Z=3-7%, X+Y+Z=100% and T' includes >=2% Hf). ...
Formula (6.94) is crucial for the theory of constitutive relations inasmuch as it demands the specification of the class of systems to be treated. The last term of the right-hand side contains the entropy flux density, which through the divergence theorem (6.44) links all other relevant flux ...
All the harmonic flux density curves go through zero at the interpolar axes. The total flux per pole is, therefore, the fundamental component plus or minus the flux of one pole-pitch of each harmonic: ‘plus’ if the harmonic has a negative peak at the positive peak of the fundamental, ...
2Definition of the Flux Footprint Let(x,z)be the alongwind and vertical coordinates. For steady-state situations with symmetry in the crosswind(y)direction, we may express the vertical mass flux density at an elevated observation pointOhaving coordinates(x,zm)as a convolution F(x,zm)=∫−...

Firstly, the analytical formula of the radial electromagnetic force of the OR-FSPM machine is analyzed and deduced in detail based on the permeance-magnetomotive force model, which shows that the air gap electromagnetic force of the low-order spatial harmonics in the OR-FSPM machine will cause...
Specifically, the particle has mass density ρ = 1.5 kg m−3 and radius R = 10−6 m. Then, the particle’s mass is m = (4π/3)ρR3 ≈ 6.3∗10−18 kg. If the surface charge density is σ = 0.5 Cm−246, the total charge is e =...

These magnetic field lines enclose the electric current and form the magnetic fluxΦ which links the coil. This flux is defined mathematically to be the integral of the magnetic flux density B→ over the surface S bounded by the coil:
In this case, the induced voltage E can be replaced in the above formula by the terminal voltage Vt. By changing the number of series turns per phase N and the pole number p of the machine flux weakening can be compensated and the machine can be operated under rated flux density under ...
