Radiofrequency (RF) transmit field (B 1) mapping is a promising method in mitigating the B 1 inhomogeneity in various magnetic resonance imaging (MRI) applications. Although several phase- or magnitude-based B 1 mapping methods have been proposed, these methods often require complex modeling, long acquisition time, or …

What is the direction of magnetic field lines?

WebInfluences of magnetic field on microscopic structures and macroscopic properties of water are studied by the spectrum techniques of infrared, Raman, visible, ultraviolet lights and X-ray. From these investigations, we know that the magnetic fields change the distribution of molecules and electrons, cause displacements and polarization of molecules and … WebThis paper presents an analytical model for calculating the detailed air-gap magnetic field distribution in interior permanent magnet synchronous motors (IPMSMs) with mixed eccentricity. In order to improve the efficiency of model solving, a modeling strategy combining the equivalent magnetic circuit network method and the subdomain method … q5 brazier\u0027s
