Relaxation is becoming increasingly important in modern stressful times. Besides special psychological practices or consuming pharmaceuticals, one can achieve a more relaxed state also by applying an appropriate magnetic field stimulation of the head (low-intensity rTMS). Following the entrainment model, we did the research using carefully chosen frequencies of modest MF intensity that followed the principles of clinical trials. Besides the situations of blind verum stimulation and the sham one, we tested also the situation that included expectations of the applied stimulation. The testing was done by electrophysiological methods and VAS. The results demonstrated an objective relaxing effect of MF stimulation, where drowsiness was not stimulated. This outcome is much more evident from electrophysiological data than from the VAS ones. From the latter results, we noticed even a slightly negative reaction to expectations.

Vigilance and attention are very important aspects of our working capacities and our general wellbeing as well. Besides taking drugs, they can in principle be achieved also by an appropriate transcranial pulsed magnetic field (MF) stimulation. In the reported research, we took the entrainment principle as the leading one, trying to enhance high beta waves with volunteers. The research conformed to clinical testing conditions. We checked the volunteers' state monitoring their physiological parameters, their responses following visual analog scale (VAS) method and their performance with the Clock test of sustained attention. In addition to observing the differences between the true stimulation and the sham one, we checked also the psychological influence on attention (additional to true stimulation). The results demonstrated overall enhanced relaxation with MF stimulation that was further improved by expectation. Relaxation, better nervous energy conservation and better performance (reduction of errors) may be concluded from all parts of the research.
