What does Earths magnetic field do for us?
The magnetic field helps us find our way around. Using a compass, we can tell which way is north even when there are no familiar landmarks in sight. The magnetic field shields us from much harmful radiation. Cosmic rays come from all directions, and the sun sends out a steady stream of high-energy particles known as the solar wind. Genesis 1:6 describes the firmament (Hebrew raqia) separating the water below from the water above. Before the flood described in Genesis, the magnetic field may even have helped to suspend the firmament above the earth. Is the Earth’s field changing? Scientists have made many careful measurements of the magnetic field over 150 years. These measurements show that the magnetic field is slowly shrinking. The intensity of the field decreases by half in 1400 years. This means that as time goes on we have less protection from cosmic radiation and the solar wind. How strong has it been? In 560 A.D. the field was twice as strong as it is now. In David’s kingdom it
