摘要

A series research has been conducted during 2012-2015, attempting to harvest abundant geomagnetic energy in Lombok island - Indonesia, resulted in three constructions of magneto-static flux manipulators, which are intended to be used for geomagnetic power plant that operates based on wireless power transfer method. Here we present the third generation of manipulator, namely `mini magneto-static flux manipulator', which consists of three concentric shielding sheets with diameters of 18.5 cm, and each sheet has 8 identical holes. Scattering of static and dynamic magnetic fields are tracked to determine the pattern of flux distribution alterations, caused by opening and closing of shielding holes. Measurements are taken in a semi-anechoic chamber with SPECTRAN NF 5035® and a pair of Helmholtz coils induces a nearly homogenous magnetic field which pattern have been three dimensional mapped in a previous research. Data of static and dynamic magnetic flux densities (each consist of 30 sample) are retrieved on 288 points for non-shielding (initial) condition and 1815 points for shielding (open and close) condition, with regular grid along 30 cm in x-, 20 cm in y-, and 20 cm in z-axis directions. Two dimensional slices are generated from three dimension maps of 1D orthogonal (x-direction) as well as 3D total component flux densities. Results show that placing of a mini manipulator also opening and closing of its shielding holes will alter magnetic field distributions in the shielded region. Even further it can convert static fields to dynamic ones. Therefore, mini magneto-static flux manipulators are more suitable to be applied for the next construction of geomagnetic power plant, considering their efficiencies which are higher than large scale manipulators.
