Introduction: Staff and patient Movement in static magnetic field MRI scanner induces current density in the human tissues, so cause biologic effects in people. The aim of this study was the Modelling of current density induced by moving individual with different velocities in static magnetic field of magnetic resonance imaging. Materials and Methods: current ...

Field-induced strains of 6% are reported in ferromagnetic Ni–Mn–Ga martensites at room temperature. The strains are the result of twin boundary motion driven largely by the Zeeman energy difference across the twin boundary. The strain measured parallel to the applied magnetic field is negative in the sample/field geometry used here. The strain saturates in fields of order 400 kA/m and is blocke...

This paper has examined the analytical solution of steady fully developed natural convective flow of a viscous incompressible and electrically conducting fluid between vertical channel by taking the Hall current and induced magnetic field into account. We have obtained the non-dimensional simultaneous ordinary differential equations using the suitable non-dimensional variables and parameters in...

In this study, effects of numerous physical quantities like dissipation, thermal radiation, and induced magnetic field on magnetohydrodynamic Casson fluid flow through a vertical plate is addressed. The non-dimensional multivariable governing equations are solved numerically by by means of Runge-Kutta method along with shooting technique. The behavior of velocity, temperature and induced magnet...

Memory effect of electric-field control on magnetic behavior in magnetoelectric composite heterostructures has been a topic of interest for a long time. Although the piezostrain and its transfer across the interface of ferroelectric/ferromagnetic films are known to be important in realizing magnetoelectric coupling, the underlying mechanism for nonvolatile modulation of magnetic behaviors remai...

We analyze the possibility of detecting weak magnetic fields by using magnetostrictive perturbation of optical fibers. The basic scheme is demonstrated in Fig. 1. A low-loss optical fiber of length L is sheathed in a magnetostrictive jacket that undergoes a longitudinal strain (magnetostriction) when immersed in a magnetic field. This strain affects the phase delay of a laser light beam propaga...
