A visual study of magnetic maps can be fruitful for preliminary interpretation (Telford et al, 1998) Visual studies of total aeromagnetic intensity contour map (Figure 2) and the residual aeromagnetic intensity contour map (Figure 3) of Wamba and its adjoining areas revealed variations in magnetic field intensity
throughout the area.
The experiments are divided into two steps: we first test the magnetic field intensity
received at port 2 with the MM lens, and then remove the MM lens and test again, while other configurations are the same.
The real part of permeability ([mu]') as a function of frequency under the magnetic field intensity
0.7 T is shown in Figure 8(a).
Acute biochemical effects appear together with the surpassing of a critical value of the magnetic field intensity
and disappear at the same time with the field disappearance; 3).
Shielding effectiveness factor [K.sub.ef] estimates the decay factor of the externally applied magnetic field intensity
[H.sub.0] transmitted into the internal cylinder [D.sub.1] .
Because the optimal dimensions were 0 to 150 micron and optimal magnetic field intensity
was 2000 Gauss, further other magnetic separation was carried out for these dimensions and field intensity.
Schematic illustration of the physical processes in ISAS, [J.sub.1,2]--the unidirectional currents induced in the screen and in the blank, [H.sub.[tau]12]--the tangential components of the magnetic field intensity
being excited by the currents [J.sub.1,2]
The probe used for the measurement of the magnetic field intensity
was a coil; this is illustrated by Figure 3.
This would also be possible with the system used in this research, but the amplitude of the magnetic field is too small for accurate determination of magnetic field intensity
where, for the moment, [B.sub.*] is a parameter related to the magnetic field intensity
The indoor positioning technology based on the magnetic field matches the magnetic field intensity
, which is obtained by the indoor moving carrier, with the geomagnetic disturbance fingerprint model to enable indoor positioning.
