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.
A qualitative picture of the
magnetic flux density lines in the xOy plane of the storage with eight coils is shown in Fig.
11 show that the
magnetic flux density at the place where section 1 makes a contact with the platform is 0.66 T and the
magnetic flux density at the place where section 2 makes a contact with platform is 0.72 T.
The mean for that is the raising of the
magnetic flux density in the air-gap of the machine.
analyzed analytically, in the limit of thin
magnetic flux tube, the dispersion relation of the kink MHD mode and have obtained that this mode is unstable against the KH instability when the critical jet velocity is equal to 4.47[v.sub.A] = 3576 km [s.sup.-1] ([v.sub.A] = 800 km [s.sup.-1] is the Alfven speed inside the jet).

8, the MR effects increased with increasing
magnetic flux density and magnetic saturation was reached at about 560 mT.
Once the magnetic vector potential A is obtained at some time step [t.sub.n+1], the
magnetic flux B and electric field E at the same time step can be calculated using Eqs.
The values of average
magnetic flux density and heterogeneity of
magnetic flux density were calculated at control zone.
Reducing
magnetic flux density is another possible solution but again, lamination costs increase by increasing the amount of magnetic material.
