Effect of The Earth’s magnetic field By X 9h Earth’s Magnetic Field Introduction Our Earth is a huge bar magnet tilted 11 degrees from the spin axis of the Earth‚ with geographic north pole being earth’s magnetic south pole and vice versa. Similar to how a magnet has a magnetic field surrounding it‚ our Earth also has its own magnetic field. The earth’s magnetic field is formed in the earth’s core due to a process known as the dynamo effect. According to dynamo effect
