By using the resulting array, we were able to improve the magnetic

flux density by 17% and the power generation efficiency of the energy harvesting device by 16% compared with the conventionally-designed 2-dimensional array.

1) with the maximum value of the magnetic

flux density [B.sub.m] depends on the size of the section, i.e.

Where, [[mu].sup.rm] is the relative permeability of the magnet, [[mu].sub.0] is the permeability of air, [l.sub.g] and [l.sub.m] are air-gap and magnet thicknesses, [T.sub.ph] is stator turns/phase, I is the current in the coil, [[mu].sub.rm] is the relative permeability of the magnet, [A.sub.g] and [A.sub.m] are air-gap and magnet areas, B is the air-gap

flux density, [B.sub.r] is the magnet remnant

flux density, k is the leakage factor, [K.sub.c] and [K.sub.h] are core loss coefficients, [P.sub.c] and [P.sub.h] are eddy current and hysteresis losses in steel and [B.sub.m] is the magnet

flux density.

The calculated value of the thermal neutron

flux density was 1817.5 neutrons/[cm.sup.2]/s and the average value of kerma rate determined on this basis amounted to 244 [micro]Gy/h, and the dose equivalent rate stood at 610 [micro]Sv/h.

No-load magnetic

flux density distribution over magnet pole and iron pole pitch of the [V.sub.1]-[U.sub.4] and [V.sub.1]-[V.sub.4] concepts.

From model 1 and model 2 obtained simulation results can be stated that the magnitude of

flux density between steel plates for model 1 is |B| = 0.01 T and for a completed magnetic circuit theory model 2 is |B| = 0.69 T (average value).

The solar

flux density at a 10.7 cm wavelength is continuously monitored at the Dominion Radio Astrophysical Observatory (DRAO).

Based on the measured temperature curves at different positions, the wall heat

flux density of each position has been determined.

Figure (11) shows the magnetic

flux density distribution for two broken rotor bars as a sample for show the effect of broken bars on the flux distribution.

Fig.2 shows the responsivity at different wavelengths at a drain to source bias of 2.21 V and a

flux density of [10.sup.12] /[m.sup.2]-s.

So this part concentrates on current density distribution and magnetic

flux density distribution graphs at different gap distances and the voltage frequency is fixed at 400 Hz.

have developed a novel tube-like PM combining a series of shorter PM rings gradually changing their shapes and remanent

flux density, but this design requires an elaborated preparation for PM rings; if the GMM in the actuator changes its size, the PM rings have to be redesigned accordingly [11].
