This paper describes a high power electromagnetic microactuator fabrication method that combines the hard magnetic Fe/Pt process, Ni/Fe permalloy magnetic circuit design, bulk micromachining, and excimer laser ablation. The hard magnetic material Fe/Pt is deposited under low temperature less than 300◦C by sputter onto a suspension diaphragm to produce a perpendicular magnetic anisotropic field....

Magnetic nerve stimulation is a noninvasive, noncontact means of exciting nerves. Magnetic stimulators generate eddy currents in tissue by producing a high-amplitude, short-duration magnetic pulse from a small coil located near the tissue. A simple circuit can generate the large coil currents necessary for magnetic nerve stimulation. Careful selection of circuit components is necessary to contr...

Multiple coupled circuit modeling (MCCM) of squirrel-cage induction motors (SCIMs), or winding function approach is the most detailed and complete analytical model used to analyze the performance of faulty SCIMs. Already, in variate papers this approach was used to 3phases SCIMs, but this paper extends the above-mentioned model to 6phases SCIMs. Various simulations of variative faults are carri...

The neural substrate subserving magnetoreception and magnetic orientation in mammals is largely unknown. Previous experiments have demonstrated that the processing of magnetic sensory information takes place in the superior colliculus. Here, the effects of magnetic field conditions on neuronal activity in the rodent navigation circuit were assessed by quantifying c-Fos expression. Ansell's mole...

This paper proposes a definition of magnetic vector potential that can be used to evaluate sparse partial inductance matrices. Unlike the commonly applied procedure of discarding the smallest matrix terms, the proposed approach maintains accuracy at middle and high frequencies and is guaranteed to be positive definite for any degree of sparsity (thereby producing stable circuit solutions). Whil...

With the development of superconducting magnets, the chances of exposure to intense static magnetic fields (SMFs) have increased. Therefore, safety concerns related to magnetic field exposure need to be studied, especially the effects of magnetic field exposure on the central nervous system. Only a limited number of studies prove a direct connection between magnetic fields and electrophysiologi...
