    The development of a multistage numerical model of an electromagnetic acoustic transducer (EMAT), with particular emphasis on an EMAT receiver, is presented. The model includes five separate modeling states: static magnetic field simulation of an electromagnet; pulsed eddy current distribution of a generic meander-line coil suspended over a conducting specimen; Lorentz force distribution due to th...

    The magnetomechanical effect for a quenched and tempered alloy steel has been studied. In most published work it has been found that stress causes the magnetization to move toward the anhysteretic magnetization. However, in the present work it was found that under special conditions the magnetization moves away from the anhysteretic when a cyclic stress is applied. This behavior is tentatively exp...

    Interactions between different types of excitations in magnetic domain walls in YIG single crystal plates are investigated by induction and magnetooptic techniques. The behavior of translational and flexural modes of the wall vibrations as a function of wall velocity was found to be asymmetric. The flexural mode amplitudes and eigenfrequencies for positive and negative wall velocities are not equa... View full abstract»

    The three-dimensional integration of the Biot-Savart law for conductors in annular sector shape, in which only a constant-density θ-directed current flows, is reported. The expressions obtained allow a quick and accurate evaluation of the components of the vector potential of the stationary magnetic field and of the magnetic induction due to this type of conductor, in iron-free media. The re... View full abstract»

    The effect of thermal processes on eddy-current losses in the structural elements of cryogenic and superconducting devices are analyzed. Maxwell's equations coupled with the heat-conduction equation are solved, taking into account the dependence of resistivity, heat capacity, and heat-transfer coefficient on temperature. Losses are analyzed as a function of magnetic field, frequency, and geometry ... View full abstract»
