In this work we establish reliable correlations between density and magnetic susceptibility in three paramagnetic granites from the Pyrenees. total, 128 sites (310 measurements >2600 ones) were studied Mont Louis-Andorra, Maladeta Marimanha granitic plutons covering main range of variability susceptibility. Regressions calculated for every body an integrated linear function was obtained enti...

In magnetic resonance electrical impedance tomography (MREIT), we try to reconstruct a cross-sectional resistivity (or conductivity) image of a subject. When we inject a current through surface electrodes, it generates a magnetic field. Using a magnetic resonance imaging (MRI) scanner, we can obtain the induced magnetic flux density from MR phase images of the subject. We use recessed electrode...

Distribution of magnetic flux density in electromagnetic (EM) flow meter is significantly important for obtaining accurate flow rate. Helmholtz coils are used to generate homogenous magnetic flux density in the cross section of flow pipe of electromagnetic (EM) flow meter is presented in this paper. In this work, a simulation model with the EM module of finite element analysis software, COMSOL ...

Aims. The stability of dissipative Taylor-Couette flows with an axial stable density stratification and a prescribed azimuthal magnetic field is considered. Methods. Global nonaxisymmetric solutions of the linearized MHD equations with toroidal magnetic field, axial density stratification and differential rotation are found for both insulating and conducting cylinder walls. Results. Flat rotati...
