Magnetic phenomena in our environment

This video explains some magnetic phenomena in our environment. Earth's magnetism is detected by some living creatures and even by human brain tissue. This sense is called magnetoreception and is still being studied because it is not clear how it works and what it is used for. Orientation in space seems to be the important goal of this ability. Even though humans have no magnetic sense, some brain tissue can sense the movement of a weak magnetic field. We also treat certain diseases with electricity and the use of powerful magnetic fields.
