In the opening study included in Horizons in World Physics. Volume 296, the authors argue that that the energy of man-made electromagnetic fields and corresponding electromagnetic radiation with frequencies starting from 0 Hz and approaching the low limit of infrared is not quantized, in contrast to molecular/atomic/nuclear electromagnetic fields/electromagnetic radiation. This study may initiate a better understanding of both the nature of man-made electromagnetic fields and their interaction with matter, especially living matter. Next, using the method of accumulation of phase shifts in the rotating frame, the attenuation function S(t) of the NMR signal from an ensemble of spin-bearing particles in a magnetic-field gradient is expressed through the particle mean square displacement in a form applicable for any kind of stationary stochastic dynamics of spins and for any times.
