 Transient simulation times for field-circuit coupled models of realistic electromagnetic devices become unacceptably high. A magnetodynamic formulation is coupled to an electric circuit analysis, yielding a sparse, symmetric and indefinite matrix. The unknown circuit currents correspond to negative eigenvalues in the matrix spectrum. The Quasi-Minimal Residual method performs better than the ...

Electromagnetic induction (EMI) sensing, in both frequency and time domains, is emerging as one of the most promising remote sensing technologies for detection and discrimination of buried metallic objects, particularly unexploded ordinance (UXO). UXO sites are highly contaminated with metallic clutter so that the major problem is discrimination not detection. This requires high fidelity forwar...

The paper deals with the electromagnetic forces in induction machines when the rotor is in cylindrical whirling motion, symmetric conical whirling motion or combination of them. These motions describe the eccentric movements of the rigid rotor in induction machines. The time stepping finite element analysis is used for solving the magnetic field, and the forces are calculated from the air gap b...

Second, finit...

To investigate the effect of electromagnetic induction on the electrical activity of neuron, the variable for magnetic flow is used to improve Hindmarsh-Rose neuron model. Simultaneously, due to the existence of time-delay when signals are propagated between neurons or even in one neuron, it is important to study the role of time-delay in regulating the electrical activity of the neuron. For th...
