NOVA | Magnetic Storm | Impact on Animals | PBS
"There's no scientific evidence that humans have this "sixth sense," though curiously, our brains do contain magnetite, the mineral thought to aid other animals' brains in detecting the field."
It is surprising to note that little interest is shown on impact of changes in magnetic fields on human mind. May be people find it amusing to watch confused birds and animals than confused human beings.
Like ghosts in the movie Sixth Sense, people see only what they want to see. They obviously do not want to see their 'so-called' negative side.
