Abstract
The principle is based on idea to create an electronic model (ES) of the magnetized real object consisting of a set of identical small elements, each of the volume of ΔVs(ES). The sources of identical magnetization are represented by inserted miniature magnetization coils supplied by the current is, radius rc and the number of turns Ni. The ES behaves like the original sample (of the same dimensions and shape) in the magnetization field Ho with external magnetic susceptibility χ(s)ext=πNir2c/(ΔVs(ES)Ho. The paper deals with the samples of the cylindrical shape inserted to the axial homogeneous magnetic field. The principle validity of given ideas and derived base relations has been proved experimentally using a 2nd-order SQUID gradiometer.
