Magnetic

flux density created by the surface current flowing over the toroidal current surface has only an azimuthal component and is concentrated inside the toroidal volume, in other words, there is no field of scattering in the idealized model.

The Table 1 includes the calculated neutron

flux density ([PHI]) as a function of the distance (L) from the edge of the paraffin block.

Since the focus of this work is on relative and not on absolute calibration, it is feasible to use the 10.7 cm solar flux measured by the DRAO to estimate an expected

flux density at the C-band: the 10.7 cm solar flux measurements are converted into other wavelengths with an uncertainty that depends on the difference in wavelength.

Beyond the surface, the

flux density decreases as the integration path gets longer, while the current that the path encloses remains the same (the total current).

Loop analysis is conducted based on the assumption that field distribution is homogeneous in radius span; therefore, the GMM rod could be modeled in its longitudinal direction as a network of magnetic circuits [24]; then Kirchhoff's Laws are employed to calculate the field intensity and

flux density; in traditional analysis, the magnetic circuit of GMA is regarded as a single magnetic loop [1,19], since in a classical tube-like PM configuration, the bias field is assumed to be uniformly distributed.

The first category is based on obtaining the

flux density due to permanent magnets and currents assuming a smooth, that is, slotless, half plane with infinite permeability, as in [10].

At first, the two-coil system with no metamaterials is simulated; the distribution of the

flux density B is displayed in Fig.

From sources we know, that the necessary results can be considered as the level of magnetic

flux density of more than 1 Tl [2].

The price to be paid is a narrower stator tooth or stator core that will increase magnetic

flux density in these regions, increasing magnetic losses.
