in this paper, the effect of magnetic field on the morphology, structure and magnetic properties of electrodeposited fecu/cu thin films was investigated. the films were deposited on au2pdag/glass substrates using electrodeposition technique in potentiostatic control. the magnetic fields of 5000 and 7000 oe were applied on deposition bath during deposition. two series of thin films were prepared...

although the promotional effects on bone healing of pulsed electromagnetic fields (pemf) have beenwell demonstrated, the effects of static magnetic fields (smf) remained unclear. in this study, effects of acustom-made magnetic wrap on radiographic and histopathological aspects of bone healing using a canineunstable osteotomy gap model were investigated. after an osteotomy of the midshaft radius...

AlfvŽn waves are ubiquitous in space plasmas and are the means by which information about changing currents and magnetic fields are communicated. Shear AlfvŽn waves radiated from sources with cross field scale size on the order of the electron inertial length, δ = c/ωpe, have properties which differ considerably from planar Magneto-hydrodynamic waves. Currents of cross field size , δ, are commo...

This paper presents the effect of centrifugal load in functionally graded (FG) hollow sphere subjected to uniform magnetic field. Analytical solution for stresses and perturbation of the magnetic field vector are determined using the direct method and the power series method. The material stiffness, the magnetic permeability and the density vary continuously across the thickness direction accor...

This article reviews the use of gyroresonance emission at radio wavelengths to measure coronal magnetic fields. The spiralling motion of electrons in the 200– 2000 G fields in the solar corona produces sufficient opacity to render the corona optically thick, making it easy to recognize such sources in microwave images from their coronal brightness temperatures. Where gyroresonance sources are p...

Atomic magnetometers have found widespread applications in precise measurement of the Earth’s magnetic field due to their high sensitivity. In these measurements, various methods have been utilized to compensate the Earth’s magnetic field in an unshielded environment. In this paper, we have proposed a method based on finding the minimum resonance frequency (corresponding to minimum magnetic fie...

The magnetic confinement of plasmas in fusion experiments can significantly degrade due to perturbations of the magnetic field. A precise analysis of the magnetic field in a stellarator-type experiment utilizes electrons as test particles following the magnetic field line. The usual fluorescent detector for this electron beam limits the provided information to two-dimensional cut views at certa...

Context. Faraday rotation measurements of extragalactic radio sources during coronal occultation allow assessment of both the electron density distribution and the three-dimensional magnetic field topology in the outer solar corona. Aims. We simulate the three-dimensional structure of both the coronal magnetic field and the electron density distribution in order to reproduce the excess Faraday ...
