Many animals make use of it for finding their way when traveling over long distances as they have the ability to be able to align themselves with the magnetic field of Earth. Bees, sea turtles and dolphins are among the animals that have a magnetic compass, allowing them to make use of information that is coded in magnetic fields. Scientists do not know if the magnetic fields are used for more than navigation. Geophysicist Joe Kirschvink, from the Institute of Technology in California, is currently testing human beings for a 6th magnetic sense. A study recently published has suggested that there is a protein in the retina of human beings that when put into fruit flies can detect magnetic fields. The research suggests that this can serve as a magneto sensor, but it is not sure if humans can use it in this way.
It is thought that if the magnetic field environment of the Earth is distributed it may cause issues with, such as sleep, mental confusion, lack of energy, feeling of being overwhelmed or on edge. If the fields are stable, but solar activity is boosted, some people have said that they feel more positive and inspired. More than likely this is down to a link between the brain of the human being, the nervous system, and cardiovascular systems.
