We show that the initial-value problem for non-relativistic magnetic dynamo equation turns out to be ill-posed in L2 norm when electromotive force depends linearly on field. This result implies increasing of energy does not necessarily come from physical amplification mechanisms, since certain modes could arbitrarily grow as wave-frequency increases, despite any process. Thus, up this order, th...

PURPOSE A multicenter study was undertaken to evaluate the safety, efficacy and cost of electromotive drug administration of intravesical lidocaine to produce bladder local anesthesia as an alternative to traditional methods of spinal or general anesthesia. MATERIALS AND METHODS A total of 94 patients were enrolled in the study who had either a history of bladder tumor that required cold cup ...

Torque and speed sensorless induction motor control is presented in this paper. The idea is realized using a sliding mode closed loop rotor flux observer for estimation of electromotive force of machine. This signal is then used in nonlinear stator flux and torque control of induction motor and in rotor flux observer for speed and flux estimation. The analysis of the proposed method is included...

An axisymmetric magnetic field is applied to a spherical, turbulent flow of liquid sodium. An induced magnetic dipole moment is measured which cannot be generated by the interaction of the axisymmetric mean flow with the applied field, indicating the presence of a turbulent electromotive force. It is shown that the induced dipole moment should vanish for any axisymmetric laminar flow. Also obse...

It is theoretically predicted that the Nernst coefficient is strongly suppressed and the thermal conductance is quantized in the quantum Hall regime of the twodimensional electron gas. The Nernst effect is the induction of a thermomagnetic electromotive force in the y direction under a temperature bias in the x direction and a magnetic field in the z direction. The quantum nature of the Nernst ...

In this paper, the evaluation of the characteristics of a new type rotating eddy-current probe for nondestructive Eddy-Current Testing (ECT) is carried out using 3-D edge-based FEM. The changes of the induced electromotive force are monitored for various inner and outer types of thin cracks inside the metal plate. It was veri ed that although the intensity of the signal obtained by this new typ...

Three-dimensional simulations of a thermally stably stratified gas with a localized layer of toroidal magnetic field are carried out. The magnetic field gives rise to a magnetic buoyancy instability. Due to the presence of rotation the resulting fluid motions are helical and lead to an α-effect, i.e. to a component of the electromotive force in the direction of the mean magnetic field. The valu...
