The energy of magnetically induced electric fields was so weak that cellular effects may not only be due to the induced electric fields. It is, therefore, important to consider all possible mechanisms including direct interaction between magnetic fields and cells.

By computer simulation of 3D distributions of the intensities of the induced electric field, factors, determining magnetic stimulation concentration and depth, are analysed and discussed. Basis for designing a reasonable coil and stimulator to achieve optimal stimulation effect are established.

Effects of 50Hz pulsing magnetic fields (PMFs) on gap junctional intercellular communication (GJIC) were studied by using microinjection, and compared with the effects of 50Hz sinusoidal magnetic fields (SMFs). The effects caused by different intensities of induced electric fields (EFs) at the same intensity of PMFs and the same exposure duration were also examined.

The study of unipolar-charged fluids in the presence of external and induced electric fields has recently taken on great importance.

This field has a component parallel to the magnetic field, with an amplitude comparable to that of the induced electric field.

For the case of excitons entrained by electrons we find the drag velocity υdrag, and for electrons entrained by excitons we compute the induced electric field E2.

By analyzing the selection rules for exchange-induced electric dipole transitions under double-exchange conditions we identify all the absorption lines of Cr3+-Cr2+ pairs.

Based on the previously suggested model of nanoscale dislocation-induced Josephson junctions and their arrays, we study the magnetic-field-induced electric polarization effects in intrinsically granular superconductors.

Effects of several types of low energy, low frequency electromagnetic fields (EMFs) on DNA synthesis in UMR 106 osteoblast like cells were investigated to explore the optimum physical parameters for stimulating cell proliferation and to provide a basis for determining its mechanism. DNA synthesis was judged using 3 H thymidine incorporation. The results showed that DNA synthesis in the cells increased with some specific combinations of the parameters (pulsed electric fields with pulse width ...

Effects of several types of low energy, low frequency electromagnetic fields (EMFs) on DNA synthesis in UMR 106 osteoblast like cells were investigated to explore the optimum physical parameters for stimulating cell proliferation and to provide a basis for determining its mechanism. DNA synthesis was judged using 3 H thymidine incorporation. The results showed that DNA synthesis in the cells increased with some specific combinations of the parameters (pulsed electric fields with pulse width 0.2ms , field strength 10V/cm, frequency 125Hz; sinusoidal electric fields with field strength 1V/cm,frequency 10 Hz; and sinusoidal magnetic fields with field density 0.5mT, frequency 5Hz). The results suggest that EMFs with some specific wave forms rather than complex forms can be used in clinical electrotherapy. In addition to frequency, field strength (or field density) within a suitable intensity played a significant role in causing DNA synthesis response. The energy of magnetically induced electric fields was so weak that cellular effects may not only be due to the induced electric fields. It is, therefore, important to consider all possible mechanisms including direct interaction between magnetic fields and cells.

Magnetic stimulation is a noninvasive diagnostic and therapeutic technique based on the principle that time varying current in coil can generate time varying magnetic field, and the magnetic field can induce current to stimulate some excitable tissues. A general model of the magnetic stimulation of excitable tissue is presented. A set of dimensionless parmeters is determined and used to make the spatial distributive function of the induced electric field have no dimensions. By computer simulation of...

In this paper, influences of coil geometry and related factors on distribution of induced electric fields during magnetic stimulation were analyzed theoretically, which includes the shape and the diameter of the coil, the ratio between diameter and stimulation depth, the gap between two coils and current direction. The different changes of induced electric field brought about by changing of these factors were calculated. The result showed the effect of localization was good, when the diameter of...

In this paper, influences of coil geometry and related factors on distribution of induced electric fields during magnetic stimulation were analyzed theoretically, which includes the shape and the diameter of the coil, the ratio between diameter and stimulation depth, the gap between two coils and current direction. The different changes of induced electric field brought about by changing of these factors were calculated. The result showed the effect of localization was good, when the diameter of the coil was 2 to 4 times of the depth of stimulation.
