The orientation of earthworms is influenced by magnetic fields

Earth has a natural magnetic field that many animals use for orientation and navigation. With the development of technology, these natural systems have been exposed to high levels of man-made electromagnetism from the heavy usage of electric devices. This study aims to understand the possible effects of artificial magnetic fields on the behavioral responses of the earthworm, which is used in this study as a model organism in laboratory conditions. The 3 experimental groups, each composed of 20 earthworms, were exposed to 190–520 µT magnetic fields using a 1.5 V current for 1-h durations in a wire-wrapped vivarium. The experimental and control groups were kept in similar conditions.
