Thermal effects are assumed to be negligible. Nonthermal reactions to induced currents include muscle and nerve stimulation, ranging from tingling in the skin to involuntary muscle contractions and cardiac arrhythmias. Peripheral muscle stimulation in humans has been noted in rapidly changing magnetic field gradients at a threshold of 60 T/second. Visual flickers of light, called magnetophosphenes, have been reported in association with rapidly changing magnetic field gradients and with rapid eye movements within a static magnetic field. Magnetophosphenes have not been reported in association with low field strength
systems, but have been reported by people working with 4.0 T scanners.
Along the characteristic lines in he working regions of the synthesized structures [S.sub.i], the local values of the magnetic field strength
H field were calculated using the tools of the Elcut program.
The protected field strength
values are in accordance with Recommendation ITU-R M.1830 Annex 2 Table IV (see Table III of this article), which complay also with the protection criteria of ARNS against DVB-T interference.
Generated calculations of magnetic field strength
and magnetic flux density figures dependency from strength of the stream flowing through strands of solenoid are presented in Tables 1 and 2 as well as Figs.
This means that the positions of maximum and minimum field strength
are predictable at a given frequency.
By increasing field strength
, however, there are other important considerations.
The general shape of the electric field is observed by plotting the distribution of the overall field strength
of the basic model at different distances from the collector plate.
Application of the Zeeman effect with 3-field modulation allows the dynamic measuring range of AAS to be expanded by factors up to 10, depending on the element to be analyzed, if the absorption measurement is made at three different magnetic field strengths
(zero, medium field, maximum field).

tunable magnet up to a field strength
at least 11.75 t (proton larmor frequency of 500 mhz).
In order to produce magnetic field strength
measurements that would allow a wide range of students to be successful with this task, a set of prewrapped solenoids was designed and calibrated.
It is considered that LID 3354s viscosity and yield stress depend only on electric field strength
