Abstract
When changes in Earth's magnetic field are measured on timescales of about 1 hour, the vertical component near most coastlines is abnormally large and correlates with the onshore horizontal component. This phenomenon is known as the geomagnetic coast effect. It is caused by electromagnetic induction occurring naturally in the Earth's surface layer.
