From the earliest times, mankind has known magnetism, revealed by the attractive and repulsive property of some special stones found in nature. Several natural rocks contain magnetic minerals. Some of these are actually of extraterrestrial origin. In the past, miraculous powers were attributed to these strange objects, which seemed to have a magical nature. In ancient Greece, there was the talk of an invisible magnetic effluvium that could seep through the pores of any material, with mysterious and incomprehensible properties at that time. It took a long time to finally come up with a plausible, scientifically correct description of what was observed in magnetic materials. Much of mysticism and unrealistic beliefs have sprung up over time as reports spread about the mysterious attractive and repulsive properties of natural magnets.
Cleopatra is said to have used a magnetic amulet on her forehead to preserve her youth. At the head is the pineal gland, which recent studies indicate as magnetically sensitive. Geomagnetism seems to be one of the environmental conditions that increase pineal activity. Significant physical, biological and health effects associated with changes in solar activity, geomagnetic activity and ionospheric concentrations of charged particles have been identified. Effects include altered blood pressure, a significant reduction in melatonin levels, increased cancer, reproductive, heart and neurological diseases.
