A Novel Approach for Quantifying Magnetic Susceptibility of Aqueous and Organic Solutions.

A new method for measuring the magnetic properties of aqueous and organic solutions is presented. This approach is based on quantifying the force resulting from the sample's interaction with a magnetic field. The experimental setup utilizes neodymium magnets attached to a stepper motor to adjust the distance between the magnets and the test sample, while an analytical balance serves as a strain gauge. Magnetic susceptibility measurements were performed on selected inorganic and organic solutions. A series of finite element simulations allowed us to convert experimental results to physical quantities describing magnetic susceptibilities of substances. The limit of detection (LoD) and limit of quantification (LoQ) values for the developed method of determining magnetic susceptibility were equal to 6.67·10-3 M and 2.02·10-2 M, respectively.

Dataset for calculating the currents and voltages induced on underground pipelines by nonparallel overhead power lines.

The electromagnetic interference caused by overhead power lines on nonparallel underground pipelines is assessed in "A numerical model for the calculation of electromagnetic interference from power lines on nonparallel underground pipelines" (Popoli et al., 2020 [1]) by segmenting the pipeline path in a number of traits parallel to the power line. The analysis requires a multi-port electrical component to be extracted for each pipeline segment by means of finite element 2D analysis; circuit analysis can then be applied to the network composed of the cascade of the multi-port electrical components in order to calculate the induced voltages and currents on the pipeline. The data in this paper consist of matrices which represent the multi-port electrical components corresponding to the segments in which the pipeline has been subdivided. These matrices can then be used as constitutive relations in network analysis, as detailed in (Popoli et al., 2019 [2]), in order to find the induced pipeline voltages and currents for different intersection angles between the pipeline and overhead power line routings.

Data on the interference induced on a buried pipeline by an overhead power line.

The data presented in this article relate to the research article "A quasi-3D approach for the assessment of induced AC interference on buried metallic pipelines" (Popoli et al., 2018) [1]. The current induced on a pipeline versus the distance between the overhead power line and the pipeline is presented. Various configurations of the overhead power line are considered. The calculations are based on method that combines 2D FEM simulations with circuital analysis.
