You are outside on a hot, hazy summer day. The atmosphere is saturated with moisture and a storm is imminent. You are walking across a large meadow ringed by trees but at the center of the field where you are, your body is vulnerable. You catch the flash of a lighting strike out of the corner of your eye. You remember the admonition that you learned as a child. Lightning is attracted to the tallest object in an area, so you begin to run for your car at the edge of the meadow field in the parking lot. You learned that getting into your car will prevent you from absorbing a lightning strike because the tires are made of rubber. The rubber prevents the electricity in the lighting from completing its grounding.<\/p>\n\n\n\n
You also learned in grade school that the earth has an electromagnetic field. We use a compass to identify the directions \u2013 these are based on the earth\u2019s magnetic resonance. Did you also realize that our bodies have an electromagnetic field? Doctors and scientists understand that our hearts function by electrical impulses, hence the electrocardiogram test that records the electrical signals that create heart rhythms.<\/p>\n\n\n
