According to researchers, the heart has a larger electromagnetic field and a higher level of intelligence than the brain: a magnetometer can measure the energy field of the heart that radiates up 3 meters around the human body. While this is certainly significant, is perhaps more impressive than the electromagnetic field projected by the horse's heart is five times greater than the human (Imagine a sphere-shaped field around you completely). The horse's electromagnetic field is also stronger than ours and can directly influence our own heart rate!
