Since the 1960's, scientists have been studying animals' ability to perceive the Earth's magnetic field (known as magnetoreception, or the magnetic sense). Evidence has accumulated that the ability of some animals to navigate long distances and find their way home is due in part to magnetoreception.
Do humans also have the magnetic sense? The current scientific consensus is no, human magnetoreception doesn't exist.
Harry Magnet doesn't agree with this consensus. Harry's interest in human magnetoreception began in 2007 as a study of his own unique navigational abilities. The most startling conclusion he has reached is that his magnetoreceptive / navigational abilities are directly connected with his psychiatric problems. The symptoms of his psychiatric disorder give him the ability to perceive whether he is north or south of (magnetic) home.
If you have a a strong science background, read Harry's research paper on his magnetoreceptive abilities.
June, 2015: Harry Magnet was mentioned in a Mysterious Universe Podcast. The entire podcast is over an hour in duration, but the relevant portion devoted to magnetoreception is about 10 minutes. The discussion turns to animal magnetoreception at 14:30. The narrators then discuss Robin Baker's human experiments at 17:35. They discuss Harry Magnet beginning at 20:00, ending at 24:15. The discussion is partly humorous, partly serious, but they give a pretty good brief summary of Harry Magnet's ideas.
