Web2. There's a lot of speculation about how changes or flips in the Earth's magnetic field would affect us, our machines, and sea turtles. I'm curious about the GPS satellites themselves. In one way they are basically an atomic clock and transmitter. But it's silly to break it down to that level. They aren't over 2000kg without significant brains. WebThe magnetic field magnitude measured at the surface of the Earth is about half a Gauss and dips toward the Earth in the northern hemisphere. The magnitude varies over the surface of the Earth in the range 0.3 to 0.6 Gauss. The Earth's magnetic field is attributed to a dynamo effect of circulating electric current, but it is not constant in ...

Web16 feb. 2024 · A magnetometer is a device used to measure the magnetic field, particularly with respect to its magnetic strength and orientation. A popular example of a magnetometer would be the compass, which is used to measure the direction of an ambient magnetic field (i.e. in this case, the earth’s magnetic field).
