--Step 3.2) Update [[??].sub.n]: For the mth subunit, m = 1,2, ..., M, calculate the

At the next step equipment for producing the electric field of the 200 kV transmission line and also measuring the
induced current should be provided.
Using this evaluation system, this study identifies the variation characteristics and the maximum variation rate of the shear modulus of MREs for six different volume fractions of CIP and for a continuously variable
induced current. The effective range for inducing currents also investigated.
From Equations (11)-(13) and (16), the
induced current on the rough surface can be expressed as
In its turn, the
induced current measured by the induction sensor should give the same value as in the case of the contact measurement method.
Figure 25 compares the variation of the
induced current calculated by using the DM approach with that derived by using the DM approach and closed-form expressions.
While the former relies on
induced currents due to the interaction of a moving liquid with an applied DC or relatively low frequency AC magnetic field, the latter aims at reconstructing conductivity distributions in a body by utilizing the eddy currents which are induced in a relatively high frequency AC magnetic field.
Note, that according to ICNIRP guidelines from 1998 [2] the current density was a main parameter for the estimation of extremely low frequency exposure effects, while the new ICNIRP guidelines from 2010 [3] propose the induced electric field instead of the
induced current. However, there is a substantial amount of results for the current density in the relevant literature for the comparison purposes, e.g., [4-13].
