Dear highly distinguished reader,
Writing a foreword to a unique, fascinating, and excellent book is a great honor. The honor is
combined with the feeling of pleasure and satisfaction as the whole creative process, the original
concept, the brilliant ideas, as well as the experimental work I have known from the very beginning.
The execution of original ideas needs enthusiasm, insistence, hard work, and first of all belief
in that the concept is correct.
Dr. János F. László had original ideas, optimism, enthusiasm, and belief. He was a highly qualified
physicist who approached the question of biological effects of static magnetic fields from the physicist’s
point of view. He aimed at obtaining legitimate evidence on the biological effects of static
magnetic field under both in vitro and in vivo circumstances. In addition, he and his coworkers,
collaborators, colleagues were not satisfied with providing merely a description of the effect of
static magnetic field, but tried to clarify the mechanism of action, the time-dependency of the effect,
and the “dose-dependency” of the SMF-induced action. Why is this important? Static magnetic
field (SMF) therapy is used by large numbers of people for self-care all over the world; however,
the SMF dosage, treatment regimens, and mechanism of action have not yet been established.
Therefore, it is of utmost importance to elucidate, first under experimental conditions, the mechanism
of action, the optimal duration to SMF exposure, and the effective dosage. The research initiated,
carried out, and permanently stimulated by János László focused on these unanswered questions.
As the book quite adequately reflects, the analysis and examination of the biological actions of
SMF were based on a well-designed systemic study. Experiments were carried out first in microorganisms
(bacteria) than in mollusks, followed by mammals (mice and rats), and finally in humans.
Thus, the book synthetizes the biological effects obtained from both animal and human subjects –
and what is exceptional is that the outcome and conclusion were based on the author’s own results
– as opposed to the data in the literature. The final goal of all the studies was to establish the potency,
efficacy, and safety of SMF which are the basis of its human application. Consequently, the
results summarized in the present book have not only importance for basic science but also for
To my greatest sorrow, the preface cannot be finished by wishing the author further successful
research and encouraging him to write the next volume about his newest findings. János László,
shortly after finishing his excellent book, passed away leaving behind him many unanswered questions and unresolved problems. The present volume, however, will convince everyone that his
oeuvre is complete, and this book which is based on wide collaboration of different fields of science
will certainly constitute a determinant reference book for a long time in the field of magnetic
