STUDIES ON MAGNETIC FIELD EXPOSURES OF DROSOPHILA MELANOGASTER AND PELVETIA FASTIGIATA A dissertation submitted in partial satisfaction of the requirements for the degree Doctor of Philosophy in Biophysics

摘要

A brief synopsis of the physics of magnetism and a discussion of the magnetic properties of biological materials are presented, in ad¬dition to a selected review of previous investigations into the biological effects of magnetic fields, as well as a discussion of hypothetical mechanisms to account for those effects, as background for the dissertation research. Two organisms were investigated. Pupae of the fruit fly, Drosophila melanogaster, were treated for brief periods by a magnetic probe, producing a magnetic field of high flux density and steep gradient.
